The below patch, to be applied using patch -p0 while in the main directory,
which I inserted (not copied and pasted) into this mail message - so it
should be OK in terms of spacing - makes "usemallocwrap='false'" the default
(overridable via command-line or manual Configure entries) for cc -n32
compiles on IRIX 6.2+. It applies on, and so far works on, both 5.8.x
(23430) and 5.9.x (23438):

Still running are the checks for -Uusemallocwrap, -32/-o32 mode, and -64
mode, but I do not anticipate any differences from the expected results in
regard to usemallocwrap (I am interested to see what happens with Math::Trig
in -32/-o32 mode on a 64-bit machine and on machines with other processors
than IP22 and IP32, and will report on any differences). I describe this as
a temporary fix because:
A. While this may be suitable for stable to _keep_ it stable, it would be
nice to make this option functional for IRIX for 5.9.x (and thence
5.10.x), if possible.
B. I don't know if this option should be turned off when using gcc without
-mabi=64.

P.S. BTW, would it be preferable if I put this in as a bug report? I wasn't
sure, since there was already discussion on it on the smokers/daily-build
list which got transferred to perl5-porters.
