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
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.
28 # Let's assume we want to use 'cc -n32' by default, unless the
29 # necessary libm is missing (which has happened at least twice)
32 if test -f /usr/lib32/libm.so

43 # Check for which version of the compiler we're running
