m4: use a safer pattern to enable/disable output
Work on some other areas of Bison revealed that some macros expanded
to be expanded only once were actually expanded several times. This

glr.cc, yacc.c: initialize yylloc properly
There are several issues to address here. One is that yylloc should
be initialized when possible. Another is that the push parser needs
to update yypushed_loc when the user modified it. And if the parser
starts by a reduction of an empty, it uses the first location on the
stack, which, therefore, must also be initialized to this initial
location.
This is getting complex, especially since because initializing a
global (impure interface) is different from initializing a local
variable. To simplify, the local yylloc is not initialized during its
definition.

yacc.c: initialize yylval and yylloc.
When generating a pure push parser, the initialization of yylval and
yylloc may not be visible to the compiler. With warnings enabled, GCC
4.3.6, 4.4.7, 4.5.4, and 4.6.3 report uninitialized uses of
yylval/yylloc. Using local pragmas to disable these warnings is not
supported before 4.6, and 4.6 does not support it properly. So
initialize yylval and yylloc at their definition. Reported by Peter
Simons. See
http://lists.gnu.org/archive/html/bison-patches/2012-10/msg00133.html
* data/c.m4 (b4_yyloc_default_define): New.
* data/yacc.c: Use it when locations are requested.
(YYLVAL_INITIALIZE): Replace by...
(YY_INITIAL_VALUE): this.
(yyparse): Initialize yylloc and yylval.
Therefore, remove the initialization of yylloc's field.

maint: be compilable with GCC 4.0
The "shadows a global declaration" warning in GCC 4.0 was a bit
annoying. It does not like that a type name be used in a prototype of
a function (not the implementation, just the declaration):
In file included from src/LR0.c:38:
src/reader.h:56: warning: declaration of 'named_ref' shadows a
global declaration
src/named-ref.h:35: warning: shadowed declaration is here
It does not like either when a global variable name is used in a
prototype. Flex 2.5.37 generates this prototype:
void gram_set_debug (int debug_flag );
* src/getargs.h, src/getargs.c (debug_flag): Rename as...
(debug): this.
Adjust dependencies.

api.prefix: do not use #define to handle YYSTYPE_IS_TRIVIAL etc.
The following mixture is insane:
#define YYSTYPE_IS_TRIVIAL PREFIX_STYPE_IS_TRIVIAL
#if (defined YYSTYPE_IS_TRIVIAL && YYSTYPE_IS_TRIVIAL)
since, of course YYSTYPE_IS_TRIVIAL is defined. Instead we could
define YYSTYPE_IS_TRIVIAL as PREFIX_STYPE_IS_TRIVIAL only when the
later is defined, but let's avoid stacking CPP on top of M4: rather, use
#if (defined PREFIX_STYPE_IS_TRIVIAL && PREFIX_STYPE_IS_TRIVIAL)
* data/glr.c, data/yacc.c: Use YYSTYPE_IS_TRIVIAL, YYSTYPE_IS_DECLARED,

2012-07-04 Akim Demaille <akim@lrde.epita.fr>
api.prefix: also rename YYDEBUG.
The testsuite in master has shown weird errors for the "Mulitple
Parsers" tests: the caller of p5.parse() received some apparently
random value, while tracing p5.parse() showed that the function was
consistently returning 0.
It happens when mixing several parser headers, some generated without
%debug, others with. In particular the C++ parser was generated with
%debug, i.e., with:
#ifndef YYDEBUG
# define YYDEBUG 1
#endif
and compiled separatedly. Yet, its header was included after the one
of another parser, this time without %debug, i.e., with
#ifndef YYDEBUG
# define YYDEBUG 0
#endif
in its header. As a result, the parser was compiled with YYDEBUG set,
but its header was used without. Since the layout of the objects are
then completely different, boom.
Therefore, do not change the value of YYDEBUG. Rather, use it as a
default value for <API.PREFIX>DEBUG.

* tests/calc.at (AT_CALC_MAIN): Missing include reported by Hydra.
2012-06-15 Akim Demaille <akim@lrde.epita.fr>
tests: call the parser from another compilation unit.
In order to improve the testing of %defines, which exports the
interface of the generated parser, change the calc.at tests so that
when %defines is passed, main will be in another compilation unit. It
loads the generated header.
* tests/calc.at (AT_CALC_MAIN): New.
Includes the definition of the global variables.
Therefore, now declare them from the %requires section of the parser.
Adjust to yydebug and yyparse being renamed by %name-prefix.

yacc.c: instead of duplicating y.tab.h inside y.tac.c, include it.

* data/yacc.c: here.
2012-06-13 Akim Demaille <akim@lrde.epita.fr>
yacc.c: factor.
yacc.c used to include two almost identical sections: one for the *.h
file, and another for the *.c file. The main difference is that in
the *.c file we used the yy* names (as %name-prefix is handled by
"#define yy* <prefix>*" before), while the *.hh used <prefix>* names.
Keep only the later. If this is troublesome, b4_shared_declarations
can easily take the desired prefix as argument.
* data/yacc.c (b4_shared_declarations): New.
Use it to factor duplicated declarations.
2012-06-12 Akim Demaille <akim@lrde.epita.fr>
skeletons: factor yacc.c and glr.c.
yacc.c and glr.c share common declarations. Their YYLTYPE are exactly
equal, and their YYSTYPE are sufficiently alike to be fused (its
declaration was protected by YYSTYPE_IS_DECLARED in yacc.c, but not in
glr.c). Besides, yacc.c duplicated the definitions of YYLTYPE and
YYSTYPE (*.h/*.c).
* data/c.m4 (b4_declare_yylstype): New.
* data/yacc.c, data/glr.c: Use it.
2012-06-12 Akim Demaille <akim@lrde.epita.fr>
glr.c: minor refactoring.

do not ignore errors like ENOSPC,EIO when writing to stdout
Standard output was never explicitly closed, so we could not
detect failure. Thus, bison would ignore the errors of writing
to a full file system and getting an I/O error on write, but only
for standard output, e.g., for --print-localedir, --print-datadir,
--help and some verbose output.
Now, "bison --print-datadir > /dev/full" reports the write failure:
bison: write error: No space left on device
Before, it would exit 0 with no diagnostic, implying success.
This is not an issue for "--output=-" or the other FILE-accepting
command-line options, because unlike most other GNU programs,
an output file argument of "-" is treated as the literal "./-",
