One of these days I'm going to write this down somewhere: GCC + Irix +
PostgreSQL does not work -- until proven otherwise and/or GCC is fixed.
(The reason that the assembly fails is unrelated to this bug; it's just
that no one ever bothered to work on it because there's no use anyway.)
I was going to suggest myself someday that we force CC=cc, but it should
be done in configure.in (near line 274) and not in the template file.

We've had successful reports for Irix in the past, so I don't think the -n
and -r flags are strictly necessary -- at least I'd like to see more
information regarding them. What makes -n32 and -r12000 better than, say,
-n64 and -r6000?

The -O2 seems okay. Its lack is probably a remnant from the old fmgr
times.
