Dan,

as an intermediate datapoint: while looking for a version of emacs that
built correctly, I found that even 23.2 didn't when using gcc 4.4 or
3.4.  Fortunately, I had a 9 years old copy of gcc 3.1 around, which was
able to build both a working emacs 23.2 and 24.0.90 (from the tarball).

I'll start digging deeper from here, but it may take a bit.
