+                            Announcing ncurses 6.2
+
+Overview
+
+   The  ncurses  (new  curses)  library  is  a free software emulation of
+   curses  in  System  V  Release  4.0 (SVr4), and more. It uses terminfo
+   format,  supports  pads  and  color  and multiple highlights and forms
+   characters and function-key mapping, and has all the other SVr4-curses
+   enhancements  over  BSD curses. SVr4 curses became the basis of X/Open
+   Curses.
+
+   In  mid-June  1995,  the  maintainer of 4.4BSD curses declared that he
+   considered  4.4BSD curses obsolete, and encouraged the keepers of unix
+   releases such as BSD/OS, FreeBSD and NetBSD to switch over to ncurses.
+
+   Since 1995, ncurses has been ported to many systems:
+     * It is used in almost every system based on the Linux kernel (aside
+       from some embedded applications).
+     * It  is  used  as the system curses library on OpenBSD, FreeBSD and
+       MacOS.
+     * It  is used in environments such as Cygwin and MinGW. The first of
+       these was EMX on OS/2 Warp.
+     * It is used (though usually not as the system curses) on all of the
+       vendor  unix  systems,  e.g.,  AIX,  HP-UX,  IRIX64, SCO, Solaris,
+       Tru64.
+     * It should work readily on any ANSI/POSIX-conforming unix.
+
+   The distribution includes the library and support utilities, including
+     * captoinfo, a termcap conversion tool
+     * clear, utility for clearing the screen
+     * infocmp, the terminfo decompiler
+     * tabs, set tabs on a terminal
+     * tic, the terminfo compiler
+     * toe, list (table of) terminfo entries
+     * tput,  utility  for  retrieving  terminal  capabilities  in  shell
+       scripts
+     * tset, to initialize the terminal
+
+   Full manual pages are provided for the library and tools.
+
+   The ncurses distribution is available at ncurses' homepage:
+
+     ftp://ftp.invisible-island.net/ncurses/ or
+     https://invisible-mirror.net/archives/ncurses/ .
+
+   It is also available via anonymous FTP at the GNU distribution site
+
+     ftp://ftp.gnu.org/gnu/ncurses/ .
+
+Release Notes
+
+   These notes are for ncurses 6.2, released February 12, 2020.
+
+   This  release  is  designed  to  be source-compatible with ncurses 5.0
+   through  6.1; providing extensions to the application binary interface
+   (ABI).  Although  the  source  can  still be configured to support the
+   ncurses  5  ABI, the reason for the release is to reflect improvements
+   to the ncurses 6 ABI and the supporting utility programs.
+
+   There  are,  of  course,  numerous  other improvements, listed in this
+   announcement.
+
+   The  most  important  bug-fixes/improvements  dealt  with user-defined
+   capabilities  in terminal descriptions. The release notes also mention
+   some other bug-fixes, but are focused on new features and improvements
+   to existing features since ncurses 6.1 release.
+
+  Library improvements
+
+    New features
+
+   There are several new features:
+     * O_EDGE_INSERT_STAY  tells  the  form  library  to optionally delay
+       cursor movement on a field edge/boundary
+     * O_INPUT_FIELD  extension to form library allows a dynamic field to
+       shrink if the new limit is smaller than the current field size.
+     * added  exit_curses  and  exit_terminfo to replace internal symbols
+       for leak-checking.
+     * added curses_trace, to replace trace().
+
+   Additionally,  to  improve  performance other changes (and extensions)
+   are provided in this release:
+     * mouse  decoding  now handles shift/control/alt logic when decoding
+       xterm's 1006 mode
+     * ncurses  now  defines a limit for wgetnstr, wgetn_wstr when length
+       is negative or "too large".
+     * reordered  loop-limit checks in winsnstr in case the string has no
+       terminating null and only the number of characters is used.
+     * there  is  now  no  buffer-size  limit  when  reading the $TERMCAP
+       variable.
+     * the  $TERMCAP  variable  may  be  interpreted  as  a fallback to a
+       terminfo entry
+     * mvcur  now decides whether to use hard-tabs, using xt, tbc and hts
+       as clues.
+     * extended  colors  are  improved  by  modifying an internal call to
+       vid_puts  to pass extended color pairs e.g., from tty_update.c and
+       lib_mvcur.c
+     * the  initialization  functions  now  avoid relying upon persistent
+       data for the result from getenv
+     * scrolling is improved:
+          + a limit check in newline_forces_scroll handles the case where
+            the row is inside scroll-margins, but not at the end.
+          + improved loop limits in _nc_scroll_window handle a case where
+            the scrolled data is a pad which is taller than the window.
+
+    Other improvements
+
+   These are revised features:
+     * used  "const"  in  some prototypes rather than NCURSES_CONST where
+       X/Open  Curses  was updated to do this, e.g., wscanw, newterm, the
+       terminfo  interface.  Also  use  "const"  for  consistency  in the
+       termcap interface, which was withdrawn by X/Open Curses in Issue 5
+       (2007).  As  of  Issue  7,  X/Open  Curses still lacks "const" for
+       certain return values, e.g., keyname.
+     * modified  wbkgd  and  wbkgrnd  to  improve compatibility with SVr4
+       curses,  changing the way the window rendition is updated when the
+       background character is modified
+     * improved  terminfo  write/read by modifying the fourth item of the
+       extended  header  to  denote  the  number  of valid strings in the
+       extended string table (see term(5)).
+     * modified   the   initialization  checks  for  mouse  so  that  the
+       xterm+sm+1006  block  will  work  with  terminal  descriptions not
+       mentioning xterm.
+
+   These were done to limit or ultimately deprecate features:
+     * deprecated  safe-sprintf, since the vsnprintf function, which does
+       what was needed, was standardized long ago.
+     * marked   vwprintw  and  vwscanw  as  deprecated;  recommend  using
+       vw_printw and vw_scanw, respectively.
+     * added  deprecation warnings for internal functions called by older
+       versions of tack.
+     * removed unused _nc_import_termtype2 function.
+
+   These are improvements to existing features:
+     * check parameter of set_escdelay, return ERR if negative.
+     * check  parameter  of  set_tabsize,  return ERR if not greater than
+       zero
+     * correct  a status-check in _nc_read_tic_entry() so that if reading
+       a hex/b64 $TERMINFO, and the $TERM does not match, fall-through to
+       the compiled-in search list.
+     * amend check for repeat_char to handle a case where setlocale() was
+       called after initscr
+     * move macro for is_linetouched inside NCURSES_NOMACROS ifndef.
+     * use _nc_copy_termtype2 rather than direct assignment in setupterm,
+       in   case   it   is  called  repeatedly  using  fallback  terminfo
+       descriptions
+     * improve   workaround   for  Solaris  wcwidth  versus  line-drawing
+       characters
+     * add  checks  in repair_subwindows to keep the current position and
+       scroll-margins inside the resized subwindow.
+     * correct  a  buffer-limit  in  write_entry.c  for  systems that use
+       caseless filenames.
+     * improved build-time utility report_offsets:
+          + add categories, e.g., "w" for wide-character, "t" for threads
+            to  make the report more readable. Reorganized the structures
+            reported to make the categories more apparent.
+          + add  NCURSES_GLOBALS  and NCURSES_PRESCREEN to report to show
+            how similar the different libtinfo configurations are.
+     * modified  some header files to ensure that those include necessary
+       files except for the previously-documented cases
+     * added  some  traces  in  initialization to show whether a fallback
+       entry is used.
+     * made minor optimization to reduce calls to _nc_reserve_pairs
+
+   These are corrections to existing features:
+     * fix  a  special  case  in  PutAttrChar  where  a cell is marked as
+       alternate-character  set,  but  the  terminal  does  not  actually
+       support the given graphic character. This would happen in an older
+       terminal such as vt52, which lacks most line-drawing capability.
+     * corrected  flag  for "seq" method of db 1.8.5 interface, needed by
+       toe on some of the BSDs.
+     * modify  comparison  in  make_hash.c  to  correct a special case in
+       collision handling for Caps-hpux11
+     * add    extended_slk_color{,_sp}   symbols   to   the   appropriate
+       package/*.{map,sym} files
+     * modify  lib_setup  to  avoid  calling pthread_self() without first
+       verifying that the address is valid, i.e., for weak symbols
+     * add  a  couple  of  broken-linker symbols to the list of versioned
+       symbols to help with link-time optimization versus weak symbols.
+
+  Program improvements
+
+   Several improvements were made to the utility programs:
+
+   clear
+
+          + improved  logic  for  clearing with the E3 extension, in case
+            the  terminal  scrolls  content  onto  its saved-lines before
+            actually  clearing  the  display, by clearing the saved-lines
+            after clearing the display
+
+   infocmp
+
+          + omit  filtering  of  "OTxx" names which are used for obsolete
+            capabilities,  when  the output is sorted by long-names. This
+            change helps when making a table of the short/long capability
+            names.
+
+   tic
+
+          + added   check   for   consistent   alternate   character  set
+            capabilities.
+          + added check for paired indn/rin.
+          + added check for terminals with parm_dch vs parm_ich.
+          + added  check  for  the  case  where setf/setb are given using
+            different   strings,   but   provide   identical  results  to
+            setaf/setab.
+          + corrected check for ich1.
+          + changed  a  too-large  terminal entry from a fatal error to a
+            warning.
+
+   toe
+
+          + ignores  any  hex/b64 $TERMINFO value in the list of terminfo
+            databases.
+
+   tset
+
+          + replace  check  in reset command for obsolete "pt" capability
+            using tbc and hts capabilities as clues
+          + modify reset to allow for tabstops at intervals other than 8.
+          + change   reset's   behavior   for  margins  to  simply  clear
+            soft-margins  if  possible,  rather  than  clearing  and then
+            setting them according to the terminal's width.
+
+   tput
+
+          + add "x" to getopt string so that "tput -x clear" works.
+
+   Several  changes were made to the generated ncurses*config scripts and
+   the   analogous   ".pc"   files  to  reduce  differences  between  the
+   configurations they report:
+     * modified the ncurse*-config and pc-files to more closely match for
+       the -I and -l options.
+     * filtered out linker-specs from the --libs report.
+     * amended  the ncurses*-config and pc-files to take into account the
+       rpath hack which differed between those files.
+     * modified  generated  ncurses*config  and  ncurses.pc, ncursesw.pc,
+       etc., to list helper libraries such as gpm for static linking.
+
+    Examples
+
+   Along  with  the  library and utilities, improvements were made to the
+   ncurses-examples.  Most  of  this  activity  aimed  at  improving  the
+   test-packages.  A few changes are more generally useful, e.g., for the
+   main   ncurses  test-program,  and  for  analyzing  traces  using  the
+   tracemunch script:
+     * improve  recovery  from  error  when  reading command-character in
+       test/ncurses.c, showing the relevant error message and not exiting
+       on EINTR.
+     * improve  tracemunch,  by keeping track of TERMINAL* values, and if
+       tracing  was first turned on after initialization, attempt to show
+       distinct screen, window and terminal names anyway.
+     * modify tracemunch to accept filename parameters in addition to use
+       as a pipe/filter.
+     * update  tracemunch  to  work  with  perl 5.26.2, which changed the
+       rules for escaping regular expressions.
+     * add some checks in tracemunch for undefined variables.
+     * modify TurnOn/TurnOff macros (in lib_vidattr.c and lib_vid_attr.c)
+       to avoid expansion of "CUR" in trace.
+
+   There are other new demo/test programs and reusable examples:
+
+   color_content
+          Demonstrate   the   color_content   and  extended_color_content
+          functions.
+
+   demo_tabs
+          A simple demo of tabs in curses.
+
+   dump_window
+          A  portable  curses screen-dump, used to compare ncurses screen
+          contents with Solaris.
+
+   pair_content
+          Demonstrate    the   pair_content   and   extended_pair_content
+          functions.
+
+   report_hashing
+          Check hash-tables used for terminfo and termcap names.
+
+   parse_rgb
+          Sample   implementation  of  the  ncurses  RGB  extension  from
+          user_caps.5, used in picsmap and savescreen programs.
+
+   A  variety  of  improvements  were made to existing programs, both new
+   features  as  well  as  options added to make the set of programs more
+   consistent.
+     * add  "-l"  option to test/background, to dump screen contents in a
+       form that lets different curses implementations be compared.
+     * add  "@"  command  to  test/ncurses F-test, to allow rapid jump to
+       different character pages.
+     * added enum, regex examples to test/demo_forms
+     * amend  Scaled256() macro in test/picsmap.c to cover the full range
+       0..1000
+     * corrected  pathname used in Ada95 sample programs for explain.txt,
+       to  work  with  test-packages, and used an awk script to split the
+       resulting pathname when it would be too long for a single line.
+     * ignore  interrupted  system-call  in  test/ncurses's command-line,
+       e.g., if the terminal were resized.
+     * improved  ifdef's  for  TABSIZE  variable,  to  help with AIX/HPUX
+       ports.
+
+  Terminal database
+
+   There are several new terminal descriptions:
+
+     alacritty,  domterm,  kitty,  mintty,  mintty-direct,  ms-terminal,
+     n7900,   nsterm-build309,  nsterm-direct,  screen5,  ti703,  ti707,
+     ti703-w, ti707-w vscode, vscode-direct, xterm-mono, xterm.js
+
+   There  are  many  changes to existing terminal descriptions. Some were
+   updates to several descriptions:
+     * use ansi+rep in a dozen places
+     * add rs1 to konsole, mlterm
+     * improve several flash capabilities with trailing mandatory delays
+     * drop   ich1   from   rxvt-basic,   Eterm  and  mlterm  to  improve
+       compatibility with old non-curses programs
+     * add/use xterm+keypad in xterm-new
+     * use xterm+sl-twm for consistency, nine places
+     * improve xm example in xterm+x11mouse and xterm+sm_1006.
+
+   while  others  affected specific descriptions. These were retested, to
+   take into account changes by their developers:
+
+     terminator, st
+
+   while  these are specific fixes based on reviewing documentation, user
+   reports, or warnings from tic:

+       putty
+     * add Smol/Rmol user-defined capability to tmux and vte-2018
+     * add Smulx user-defined capability to tmux, vte-2018
+
+  Documentation
+
+   As usual, this release
+     * improves documentation by describing new features,
+     * attempts  to  improve the description of features which users have
+       found confusing
+     * fills  in overlooked descriptions of features which were described
+       in the NEWS file but treated sketchily in manual pages.
+
+   In  addition  to  providing  background  information  to explain these
+   features   and   show   how   they  evolved,  there  are  corrections,
+   clarifications, etc.:
+     * Corrections:
+          + correct  error-returns  listed in manual pages for a few form
+            functions
+          + corrected  prototypes  in  several  manpages  using script to
+            extract those in compilable form.
+          + fix typo in term.5, improve explanation of format
+     * Clarify in manual pages that vwprintw and vwscanw are obsolete.
+       They have not been part of X/Open Curses since 2007.
+     * New/improved history and portability sections:
+          + curs_addch.3x gives some background for ACS symbols.
+          + curs_getcchar.3x  explains  a  difference between ncurses and
+            X/Open Curses.
+          + curs_getstr.3x  gives  historical/portability  background for
+            the length parameter of wgetnstr.
+          + curs_slk.3x  lists  a few differences between SVr4 curses and
+            X/Open Curses for soft-keys.
+          + curs_terminfo.3x  explains that the initial implementation of
+            terminfo  in  SVr2 was mostly replaced by other developers in
+            SVr3.
+          + infocmp.1  explains  that the initial version of terminfo had
+            no  tool  for decompiling descriptions. That came later, with
+            SVr3, with a different developer.
+          + tabs.1 tells more than you wanted to know about the tool.
+          + tic.1  explains  that  the  initial version of terminfo had a
+            rudimentary  tool  (based  on termcap) for compiling entries.
+            The tool used with Unix was developed by others for SVr3.
+          + toe.1 explains the origin of this tool.
+     * Improvements for user_caps.5:
+          + mention meml, memu and box1
+          + expanded description of XM
+          + add a clarification regarding the RGB capability.
+          + mention user_caps.5 in the tic and infocmp manual pages.
+     * Other improvements:
+          + curs_add_wch.3x  adds  note about Unicode terminology for the
+            line-drawing characters.
+          + curs_color.3x   improves  discussion  of  error  returns  and
+            extensions.
+          + curs_mouse.3x  explains how the kmous and XM capabilities are
+            used for xterm-mouse input.
+          + curs_refresh.3x  improves documentation regarding the virtual
+            and physical screens.
+          + curs_util.3x  mentions  a  difference between SVr4 and X/Open
+            Curses for unctrl.h
+          + curs_variables.3x   improves  description  of  the  init_tabs
+            capability and TABSIZE variable.
+          + ncurses.3x   improves  documentation  regarding  feature-test
+            macros in curses.h
+          + resizeterm.3x   about   top-level  windows  which  touch  the
+            screen's borders.
+          + tput.1 clarifies how tput determines the terminal size.
+
+   There  are  no new manual pages (all of the manual page updates are to
+   existing pages).
+
+   Some  of  the  improvements  are  more subtle, relating to the way the
+   information  is presented. For instance, the generated terminfo.5 file
+   uses  a  different  table  layout,  allowing  it  to use space on wide
+   terminals more effectively.
+
+  Interesting bug-fixes
+
+   While  there  were  many bugs fixed during development of ncurses 6.2,
+   only  a  few  (the  reason  for  this release) were both important and
+   interesting. Most of the bug-fixes were for local issues which did not
+   affect  compatibility across releases. Since those are detailed in the
+   NEWS file no elaboration is needed here.
+
+   The  interesting  bugs  were in tic/infocmp's handling of user-defined
+   capabilities.  These  were  not recent bugs. Initially it was a simple
+   problem:
+     * The  user-defined capabilities can be any type (boolean, number or
+       string),  but  once given a type all uses of the name must conform
+       to  that  type--unless  some  special  support  for  a  particular
+       multi-typed name is built into ncurses.
+     * One of simpleterm's contributors copied some definitions for using
+       tmux's user-defined capabilities in late in 2016.

+
+     * Later,  in (referring to a version from mid-2017), a user asked to
+       have it updated in ncurses.
+     * However,  it  had  an  error  from  the  change  in late 2016. The
+       terminal description made what tmux expected to be string actually
+       a boolean.
+       Over  the  years,  there  were  problems with each of simpleterm's
+       terminal  descriptions.  I  repaired those, and usually dealt with
+       the problem.
+     * The  difference  in this case was that when compiling the terminal
+       database, tic may have in memory the definitions for more than one
+       terminal  description  (so  that  it  can resolve "use=" clauses).
+       Seeing   two  different  types  for  the  same  name,  in  certain
+       situations  it  would  incorrectly merge the symbol tables for the
+       two terminal descriptions.
+     * On  simpleterm's  side,  their bug was finally fixed in late 2019,
+       three years after the bug was created.
+
+   For  ncurses,  the  elapsed  time  to fix this bug was less than three
+   years.  Someone reported a problem with the terminal description a few
+   weeks  after  releasing  ncurses 6.1 (in tmux #1264), and the terminal
+   description was updated that week (ncurses patch 20180224):
+
+20180224
+        + modify _nc_resolve_uses2() to detect incompatible types when merging
+          a "use=" clause of extended capabilities.  The problem was seen in a
+          defective terminfo integrated from simpleterm sources in 20171111,
+          compounded by repair in 20180121.
+        + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
+
+   The larger part of that change added a check to prevent a simple merge
+   of  terminal  descriptions  where  the same user-defined name was used
+   with different types. But it raised some questions:
+     * Was  there  a  reliable  way to manage terminal descriptions which
+       used the same extended name in different ways?
+     * Should  ncurses  provide  a registry of well-known extended names,
+       with their types?
+
+   Since  the  correction to terminfo.src could have been readily adopted
+   by  packagers,  there  was  nothing  more  to  be  done  from ncurses'
+   standpoint  on that part. But improving ncurses to prevent issues like
+   that is the reason for making a release.
+
+   Nothing  more  (constructive) was mentioned with regard to simpleterm.
+   But  a  few  problems  were  found  in  the  handling  of user-defined
+   capabilities:
+     * Forward-references to user-defined capabilities in a "use=" clause
+       did  not  allocate  new  data  for  each  use.  In tic, successive
+       compilation   of   terminal   entries   could   add   user-defined
+       capabilities to the wrong terminal entry.
+       This  was  not noticed before, since xterm's terminal descriptions
+       were  the main users of the feature, and almost all of the uses of
+       the building-blocks which contained user-defined capabilities were
+       backward-references.
+     * There  is  one  (documented)  case  where  ncurses  6.1 supports a
+       user-defined  capability that could be any type (i.e., "RGB"). The
+       check  added  in February 2018 to guard against mismatches did not
+       handle all of the combinations needed.
+
+   Both  of  these  issues  dated  from  the  original  implementation of
+   user-defined  capabilities.  Fixing  them does not change the terminal
+   database, but a older tic without the fixes will not be able to handle
+   terminfo  sources  which rely upon those fixes. Starting in June 2019,
+   the  download  link  for  the  terminfo source file was capped at that
+   date. The development sources have an up-to-date copy of the file, for
+   people with a legitimate need for it.
+
+   The  "-c"  (check) option of tic is not very useful if it cannot offer
+   advice on parameters needed for user-defined capabilities. The various
+   Caps  files  were  reorganized to reduce redundancy, and in the common
+   portion  (Caps-ncurses),  a  registry  of user-defined capabilities is
+   provided for use by tic. While users can still define their own custom
+   capabilities,  tic  will not offer any advice when their parameters do
+   not match.
+
+   In  ncurses  6.2, tic makes a special check to allow any type for RGB,
+   but  its  being  able to do this relies upon fixes made in the ncurses
+   library in mid-2019.
+
+  Configuration changes
+
+    Major changes
+
+   There  are  no  major  changes. Several new options were added to ease
+   integration  of packages with systems using different versions of GNAT
+   and ncurses. Also, improvements were made to configure checks.
+
+    Configuration options
+
+   There are a few new/modified configure options:
+
+   --with-config-suffix
+          helps  work  around  a  filename  conflict with Debian packages
+          versus test-packages.
+
+   --with-ada-libname
+          allows  one  to  rename  the  "AdaCurses" library (at least one
+          packager prefers a lowercase name).
+
+   --with-fallbacks
+          now ensures there is a value, and adds the fallback information
+          to top-level Makefile summary.
+
+   --with-pcre2
+          check for pcre-posix library to help with MinGW port.
+
+   --with-tic-path and
+
+   --with-infocmp-path
+          help  work  around  problems  building  fallback  source  using
+          pre-6.0 tic/infocmp.
+
+   --with-versioned-syms
+          option value can now be a relative pathname.
+
+  Portability
+
+   Many  of  the  portability  changes  are implemented via the configure
+   script:
+     * ignore $TERMINFO as a default value in configure script if it came
+       from the infocmp -Q option.
+     * distinguish  gcc  from  icc  and  clang when the --enable-warnings
+       option   is   not   used,  to  avoid  unnecessary  warnings  about
+       unrecognized inline options
+     * consistently  prepend  new  libraries  as  they  are  found during
+       configuration,  rather  than  relying  upon  the linker to resolve
+       order dependencies of libraries.
+     * modified  configure  scripts  to  reduce  relinking/ranlib  during
+       library install :
+          + use  "install -p" when available, to avoid need for ranlib of
+            static libraries.
+          + scripts which use "--disable-relink;" add a 1-second sleep to
+            work around tools which use whole-second timestamps, e.g., in
+            utime rather than the actual file system resolution.
+     * add configure check for getenv to work around implementation shown
+       in  Emscripten  which overwrites the previous return value on each
+       call.
+       Use  that  to optionally suppress START_TRACE macro, whose call to
+       getenv may not work properly
+     * change  target configure level for _XOPEN_SOURCE to 600 to address
+       use of vsscanf and setenv.
+     * reduce  use of _GNU_SOURCE for current glibc where _DEFAULT_SOURCE
+       combines with _XOPEN_SOURCE
+       Allow  for  Cygwin's  newlib when checking for the _DEFAULT_SOURCE
+       symbol.
+       MidnightBSD   is   now   checked   for  the  _XOPEN_SOURCE-related
+       definitions.
+     * If the check for va_copy or __va_copy fails,
+          + configure  now  tries copying the pointers for va_list, or as
+            an array.
+          + alternatively, it checks for __builtin_va_copy(), which could
+            be used with AIX xlc in c89 mode.
+     * several changes to support a port to Ultrix 3.1:
+          + check if "b" binary feature of fopen works
+          + check for missing feature of locale.h
+          + add fallback for strstr() in test-programs
+          + add fallback for STDOUT_FILENO in test-programs
+     * The test/configure script (used for ncurses-examples) is improved:
+          + work around non-ncurses termcap.h file, e.g., in Slackware.
+          + check for TABSIZE variable.
+          + checks  for  the  X11/Intrinsic.h  header, accommodate recent
+            MacOS changes which largely emptied /usr/include.
+
+   Here are some of the other portability fixes:
+     * added  dummy  "check"  rule  in  top-level  and  test-Makefile  to
+       simplify building test-packages for ArchLinux.
+     * dropped   library-dependency   on  psapi  for  MinGW  port,  since
+       win_driver.c   defines   PSAPI_VERSION   to   2,   making  it  use
+       GetProcessImageFileName from kernel32.dll
+     * made  build-fixes  for  configuration  using --program-suffix with
+       Ada95,  noticed  with  MacOS  but  applicable  to  other platforms
+       without libpanelw, etc.
+     * modified  ncurses/Makefile.in  to  fix a case where Debian/testing
+       changes to the ld --as-needed configuration broke ncurses-examples
+       test packages.
+     * used   _WIN32/_WIN64   in  preference  to  __MINGW32__/__MINGW64__
+       symbols  to simplify building with Microsoft Visual C++, since the
+       former are defined in both compiler configurations.

+
+Features of ncurses
+
+   The  ncurses  package  is  fully upward-compatible with SVr4 (System V
+   Release 4) curses:
+     * All of the SVr4 calls have been implemented (and are documented).
+     * ncurses  supports  all  of  the for SVr4 curses features including
+       keyboard  mapping,  color,  forms-drawing with ACS characters, and
+       automatic recognition of keypad and function keys.
+     * ncurses  provides  these SVr4 add-on libraries (not part of X/Open
+       Curses):
+          + the  panels  library,  supporting  a  stack  of  windows with
+            backing store.
+          + the   menus   library,  supporting  a  uniform  but  flexible
+            interface for menu programming.
+          + the   form   library,   supporting  data  collection  through
+            on-screen forms.
+     * ncurses's  terminal database is fully compatible with that used by
+       SVr4 curses.
+          + ncurses  supports user-defined capabilities which it can see,
+            but  which are hidden from SVr4 curses applications using the
+            same terminal database.
+          + It  can  be optionally configured to match the format used in
+            related systems such as AIX and Tru64.
+          + Alternatively,  ncurses  can  be  configured  to  use  hashed
+            databases  rather  than  the  directory of files used by SVr4
+            curses.
+     * The ncurses utilities have options to allow you to filter terminfo
+       entries for use with less capable curses/terminfo versions such as
+       the HP/UX and AIX ports.
+
+   The ncurses package also has many useful extensions over SVr4:
+     * The  API  is 8-bit clean and base-level conformant with the X/OPEN
+       curses  specification, XSI curses (that is, it implements all BASE
+       level  features,  and  most  EXTENDED  features). It includes many
+       function calls not supported under SVr4 curses (but portability of
+       all calls is documented so you can use the SVr4 subset only).
+     * Unlike  SVr3 curses, ncurses can write to the rightmost-bottommost
+       corner  of  the  screen  if  your terminal has an insert-character
+       capability.
+     * Ada95 and C++ bindings.
+     * Support  for mouse event reporting with X Window xterm and FreeBSD
+       and OS/2 console windows.
+     * Extended mouse support via Alessandro Rubini's gpm package.
+     * The  function  wresize  allows  you  to resize windows, preserving
+       their data.
+     * The  function  use_default_colors allows you to use the terminal's
+       default colors for the default color pair, achieving the effect of
+       transparent colors.
+     * The functions keyok and define_key allow you to better control the
+       use of function keys, e.g., disabling the ncurses KEY_MOUSE, or by
+       defining  more  than  one  control  sequence to map to a given key
+       code.
+     * Support for 256-color terminals, such as modern xterm.
+     * Support for 16-color terminals, such as aixterm and modern xterm.
+     * Better  cursor-movement  optimization.  The package now features a
+       cursor-local-movement computation more efficient than either BSD's
+       or System V's.
+     * Super   hardware   scrolling   support.   The  screen-update  code
+       incorporates  a novel, simple, and cheap algorithm that enables it
+       to  make  optimal  use  of hardware scrolling, line-insertion, and
+       line-deletion  for  screen-line  movements. This algorithm is more
+       powerful than the 4.4BSD curses quickch routine.
+     * Real  support  for  terminals  with  the  magic-cookie glitch. The
+       screen-update  code  will  refrain from drawing a highlight if the
+       magic-   cookie  unattributed  spaces  required  just  before  the
+       beginning  and  after the end would step on a non-space character.
+       It  will  automatically  shift  highlight boundaries when doing so
+       would  make it possible to draw the highlight without changing the
+       visual appearance of the screen.
+     * It  is  possible to generate the library with a list of pre-loaded
+       fallback  entries linked to it so that it can serve those terminal
+       types  even  when  no  terminfo tree or termcap file is accessible
+       (this  may  be useful for support of screen-oriented programs that
+       must run in single-user mode).
+     * The tic/captoinfo utility provided with ncurses has the ability to
+       translate  many  termcaps  from  the XENIX, IBM and AT&T extension
+       sets.
+     * A BSD-like tset utility is provided.
+     * The ncurses library and utilities will automatically read terminfo
+       entries  from  $HOME/.terminfo  if  it exists, and compile to that
+       directory  if  it  exists  and the user has no write access to the
+       system  directory.  This feature makes it easier for users to have
+       personal  terminfo  entries without giving up access to the system
+       terminfo directory.
+     * You  may  specify  a  path  of  directories to search for compiled
+       descriptions  with  the  environment  variable TERMINFO_DIRS (this
+       generalizes  the  feature  provided by TERMINFO under stock System
+       V.)
+     * In  terminfo  source files, use capabilities may refer not just to
+       other entries in the same source file (as in System V) but also to
+       compiled  entries  in  either the system terminfo directory or the
+       user's $HOME/.terminfo directory.
+     * The  table-of-entries  utility  toe makes it easy for users to see
+       exactly what terminal types are available on the system.
+     * The library meets the XSI requirement that every macro entry point
+       have  a  corresponding  function  which may be linked (and will be
+       prototype-checked)  if  the  macro  definition  is  disabled  with
+       #undef.
+     * Extensive  documentation  is  provided (see the Additional Reading
+       section of the ncurses FAQ for online documentation).

+Development activities
+
+   Zeyd  Ben-Halim  started  ncurses  from  a  previous  package pcurses,
+   written  by  Pavel  Curtis.  Eric  S.  Raymond  continued development.
+   Juergen Pfeifer wrote most of the form and menu libraries.
+
+   Ongoing development work is done by Thomas E. Dickey. Thomas E. Dickey
+   has  acted  as  the maintainer for the Free Software Foundation, which
+   holds  a  copyright on ncurses for releases 4.2 through 6.1. Following
+   the release of ncurses 6.1, effective as of release 6.2, copyright for

+dnl -----------------
+dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
+dnl character-strings.
+dnl
+dnl It is ambiguous because the specification accommodated the pre-ANSI
+dnl compilers bundled by more than one vendor in lieu of providing a standard C
+dnl compiler other than by costly add-ons.  Because of this, the specification
+dnl did not take into account the use of const for telling the compiler that
+dnl string literals would be in readonly memory.
+dnl
+dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
+dnl let the compiler decide how to represent Xt's strings which were #define'd. 
+dnl That does not solve the problem of using the block of Xt's strings which
+dnl are compiled into the library (and is less efficient than one might want).
+dnl
+dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both

+dnl
+dnl The header files may be installed as either curses.h, or ncurses.h (would
+dnl be obsolete, except that some packagers prefer this name to distinguish it
+dnl from a "native" curses implementation).  If not installed for overwrite,
+dnl the curses.h file would be in an ncurses subdirectory (e.g.,
+dnl /usr/include/ncurses), but someone may have installed overwriting the
+dnl vendor's curses.  Only very old versions (pre-1.9.2d, the first autoconf'd
+dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
+dnl the header.
+dnl
+dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
+dnl is already in the include-path, don't even bother with this, since we cannot
+dnl easily determine which file it is.  In this case, it has to be <curses.h>.
+dnl
+dnl The optional parameter gives the root name of the library, in case it is
+dnl not installed as the default curses library.  That is how the
+dnl wide-character version of ncurses is installed.

+dnl --------------
+dnl --------------
+dnl Attempt to determine the appropriate CC/LD options for creating a shared
+dnl library.
+dnl
+dnl Notes:
+dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
+dnl the build-tree, i.e., by making use of the libraries that are compiled in
+dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
+dnl shared library since that can lead to unexpected results at runtime.
+dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
+dnl libraries are compiled in ../../lib
+dnl
+dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
+dnl to install symbolic links to the rel/abi versions of shared libraries.
+dnl
+dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
+dnl version when making symbolic links.
+dnl
+dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
+dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
+dnl (ex: libncurses.so.<ver>).
+dnl
+dnl Some loaders leave 'so_locations' lying around.  It's nice to clean up.
