I tried that, though admittedly by editing the specs directly, but gcc
choked on me:

while the equivalent modification of cpp_spec proper worked this way:

I recall that I had the same problem when adding -P to the Solaris 2/x86
CPP_SPEC (cf. config/i386/sol2.h).

I can try again with a fresh build, though.

Btw., did you have a chance to have a look at the IRIX 6 O32 patch?
