SOunds good.  I was starting to look at building a cross-compiler
based on 2.95.3, putting that in the path, and then proceeding to
install the headers.  I never got around to making it work since I've
been trying to get m68k-elf for ColdFire to build for gcc-3.2.3 and
gcc-3.3...

I've got my sledgehammer out and I'm pounding on trees :-)

No problem.  I'm sure you were just as distressed as I was.
Thanx fro looking at the problem.
