Bummer.  Is that fixed in cvs as well?  I thought I looked at
multilib.am before mailing and saw all the definitions there.

There is occasional talk of doing a libffi release separate from the
gcc tree.  There are other users, but I think they usually work by
importing the source into their own tree.

Anthony (CCd) could say better than me whether we need to preserve the
SGI MIPS compiler support.  Left to me, I say delete it.  We can
always resurrect it in the unlikely case we need it.
