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

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

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