Has anybody gotten m68k to build in 0.9.29?

So that would be a "no", then.

To reproduce the bug:
tar xvjf tip.tar.bz2
[ add the attached patch to sources/patches ]
That's pretty much all I know about it at the moment. That and moving from
4.1.2->4.2.2 didn't fix it. :(

Alas, upgrading to gcc 4.2 broke arm soft float. (Ok, it was broken in gcc
4.1 too, but I had a patch to fix it there, and adapting it to gcc 4.2 didn't
work. They let M.C. Escher have another go at the makefiles...) I plan to
upgrade someday, but for right now I've got higher priority todo items and
reverted the upgrade until I get some other things cleared.
The problem is that gcc the gcc developers moved the soft float functions in
libgcc_s.so, and if you build the compiler with --disable-shared they have to
move back to libgcc.a. You have to patch gcc to accomplish this, and the
build changed enough between 4.1 and 4.2 that a straightforward adaptation of
the patch doesn't work. (I'm working on it, but since gcc 4.2 has no obvious
advantages over 4.1 so far, it's low priority.)
That said, I can try to take a whack at SVN for diagnostic purposes. Maybe
later this evening. (I just can't _deploy_ it in the short term. And if it
_does_ fix it, maybe I can binary search for the fix. But if 4.2 didn't, and
there's nothing in the bug tracker, I kind of doubt it was specifically
