I also recently had to compile 103p1 on a 2.6 linux kernel and got the
same result.  After playing with it a little bit I discovered that the
problem seems to be with the GC and that if you run "configure" with
the right flag to use the Senora GC instead of the default Boehm GC
you should be fine.  From what I remember you might also have to fix a
few things in a C++ file somewhere but gcc was kind enough to tell me
where and how, so it wasn't really a problem.
