 #   cc -n32 update info from Krishna Sethuraman, krishna@sgi.com.
 #       additional update from Scott Henry, scotth@sgi.com

 # Futzed with by John Stoffel <jfs@fluent.com> on 4/24/1997
 #    - assumes 'cc -n32' by default
 #    - tries to check for various compiler versions and do the right
 #      thing when it can
 #    - warnings turned off (-n32 messages):
 #       1184 - "=" is used where where "==" may have been intended
 #       1552 - variable "foo" set but never used

 # Tweaked by Chip Salzenberg <chip@perl.com> on 5/13/97
 #    - don't assume 'cc -n32' if the n32 libm.so is missing

 # Threaded by Jarkko Hietaniemi <jhi@iki.fi> on 11/18/97
 #    - POSIX threads knowledge by IRIX version

 # gcc-enabled by Kurt Starsinic <kstar@isinet.com> on 3/24/1998

 # 64-bitty by Jarkko Hietaniemi on 9/1998

 # Martin Pool added -shared for gcc on 2004-01-27

 # Use   sh Configure -Dcc='cc -n32' to try compiling with -n32.
 #     or -Dcc='cc -n32 -mips3' (or -mips4) to force (non)portability
 # Don't bother with -n32 unless you have the 7.1 or later compilers.
 #     But there's no quick and light-weight way to check in 6.2.

 # NOTE: some IRIX cc versions, e.g. 7.3.1.1m (try cc -version) have
 # been known to have issues (coredumps) when compiling perl.c.
 # If you've used -OPT:fast_io=ON and this happens, try removing it.
 # If that fails, or you didn't use that, then try adjusting other
 # optimization options (-LNO, -INLINE, -O3 to -O2, etcetera).
 # The compiler bug has been reported to SGI.
 # -- Allen Smith <allens@cpan.org>

 # Modified (10/30/04) to turn off usemallocwrap (PERL_MALLOC_WRAP) in -n32
 # mode - Allen.

	# Futzed with by John Stoffel <jfs@fluent.com> on 4/24/1997
	# - assumes 'cc -n32' by default
	# - tries to check for various compiler versions and do the right

	# - warnings turned off (-n32 messages):
	# 1184 - "=" is used where where "==" may have been intended

	# Tweaked by Chip Salzenberg <chip@perl.com> on 5/13/97

	# Don't bother with -n32 unless you have the 7.1 or later compilers.

	# NOTE: some IRIX cc versions, e.g. 7.3.1.1m (try cc -version) have
	# been known to have issues (coredumps) when compiling perl.c.
	# If you've used -OPT:fast_io=ON and this happens, try removing it.
