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 |
