Right now Tom Fitzsimmons is working on upgrading libgcj.  And
Michael Koch has already done libltdl.

I'd like us to pick single blessed versions of various and use them
consistently.  Ideally this would be a pure upstream version, no
vendor hacks allowed (to reduce the "is this patch normal?" traffic we
see from time to time).

I recently suggested autoconf 2.58 and automake 1.7.9 on the gcj list,
but only because that is what I believed libstdc++ to be using (which
I found via inspection...).

Moving to automake 1.8 is fine by me, I'm sure we won't have problems
with that.  (Actually, for libgcj to make progress, we're probably
going to need to push some patches into automake and get another
release made... there's a whole other thread about this.)
