I've build GCC 2.95.2 on IRIX 5.2 without any need for hacking.  But
then, I was using an older version of GCC as the bootstrap compiler.

IIRC, Jim Wilson once told me some old version of SGI's C compiler
would mis-compile stage1 in a way that would cause some optimizations
to be missed, and then stage2 would end up different from stage3, that
would catch up on the optimizations.  Once you get a compare failure,
try `make bootstrap2' again, so that stage3 is used as stage2, a new
stage3 is built and compared with it.
