# 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):
# 1116 - non-void function should return a value
# 1048 - cast between pointer-to-object and pointer-to-function
# 1042 - operand types are incompatible
# 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
# 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.
