You forgot to look into ports/ as well.  We have a gcc 3.2.3 in there.
And it will switch to 3.3 sometimes this month, hopefully, and there will
be a snapshot of 3.4 around at that point.

Both of them will need a gas with a.out + pic support to be useful on m68k 
for the time being.

I don't have the faintest idea when binutils work will happen. Switching
m68k to ELF might be relatively easy (after all, we have some expertise
in that area now), or it might run into a show-stopper.

Sorry, but I don't agree.

I hope I'm going to get time to check whether switching to non-MIT syntax
works with the gas we have in-tree on an m68k platform.

But your argument doesn't really hold.  Right now, dropping m68k MIT
support in gcc  exactly amounts to dropping m68k-*-openbsd support.
