Class.h occurs in my source tree and not in my build tree.

I'm not sure I understand.  I don't know what kind of bug in egcs this
might be.

With glibc 2.1.1 ?  That's the most likely source of difficulty.
(Given that everything else seems to need to be patched to work with
it...  RedHat 5.2 to 6.0 is the least compatible move I've made since

Sorry, I don't really grok how egcs and the parts of libgcj all fit
together (what's a .lo file?) so I'm not sure where to poke.
