31 # or -Dcc='cc -n32 -mips3' (or -mips4) to force (non)portability
32 # Don't bother with -n32 unless you have the 7.1 or later compilers.
33 # But there's no quick and light-weight way to check in 6.2.
35 # NOTE: some IRIX cc versions, e.g. 7.3.1.1m (try cc -version) have
36 # been known to have issues (coredumps) when compiling perl.c.

38 # If that fails, or you didn't use that, then try adjusting other
39 # optimization options (-LNO, -INLINE, -O3 to -O2, etcetera).
40 # The compiler bug has been reported to SGI.
