I've got it building fairly well.  Only a few patches were needed.
Haven't run the regression tests, though.

Has a gcc bug been filed already?  If not, I can
try to put together minimal test cases, and if
they turn out to be real, file a bug.

(Generally, when I've seen that error
building random applications with earlier gcc's,
gcc has been right.  I can certainly imagine gcc-4.0
being wrong, though.)
