29 # Martin Pool added -shared for gcc on 2004-01-27
31 # Use sh Configure -Dcc='cc -n32' to try compiling with -n32.
32 # or -Dcc='cc -n32 -mips3' (or -mips4) to force (non)portability
33 # Don't bother with -n32 unless you have the 7.1 or later compilers.
34 # But there's no quick and light-weight way to check in 6.2.
36 # NOTE: some IRIX cc versions, e.g. 7.3.1.1m (try cc -version) have
37 # been known to have issues (coredumps) when compiling perl.c.
38 # If you've used -OPT:fast_io=ON and this happens, try removing it.
39 # If that fails, or you didn't use that, then try adjusting other
