11# Futzed with by John Stoffel <jfs@fluent.com> on 4/24/1997
12# - assumes 'cc -n32' by default
13# - tries to check for various compiler versions and do the right
14# thing when it can
15# - warnings turned off (-n32 messages):
16# 1116 - non-void function should return a value
17# 1048 - cast between pointer-to-object and pointer-to-function
18# 1042 - operand types are incompatible
19
20# Tweaked by Chip Salzenberg <chip@perl.com> on 5/13/97
21# - don't assume 'cc -n32' if the n32 libm.so is missing

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

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