OK, but where are the latest patches to gcc-2.8.1 ? Im looking for
2.8.1.0.xx whatever xx is, or even gcc-2.8.2 if that exists.
Is the machine description language the same for egcs and gcc?
what about the macros?
I really don't want to bite off more work porting to egcs, the project
is already way too complex.

OK, I'll try a newer glibc.

Extra credit: anyone care to clue me in on how to implement 64-bit support
in the machine description file of a machine that only has 32-bit int math?
The current i370.md confuses 64-bit floats which the machine supports, with
64-bit ints, which the machine does not and thus its a real ugly mess.
In particular, will any patches for gcc be portable to egcs?
