I failed to apply the patch on gcc-2.95.2:
(brian) /src/sicstus/jojo/gcc-2.95.2 -> patch < ../gcc-irix6-patch.txt
Hmm... Looks like a unified diff to me...
The text leading up to this was:

--------------------------
Patching file gcc/config/mips/iris6.h using Plan A...
patch: **** malformed patch at line 11: %{mabi=n32:-mips3} %{mabi=64:-mips4}}"
I tried to apply the patch manually, but that didn't help.
The patch at http://gcc.gnu.org/ml/gcc-patches/1999-06/msg00562.html does
seem to be mangled, though.
