12 # - assumes 'cc -n32' by default
13 # - tries to check for various compiler versions and do the right
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

30 # Don't bother with -n32 unless you have the 7.1 or later compilers.
31 # But there's no quick and light-weight way to check in 6.2.
