"Internal error--unrecognizable insn" always means a bug in gcc.  You
should report this to the egcs people (egcs-bugs@cygnus.com).  glob.c
is pretty awful to dig through, so you need to cut it down a bit
first.

Make printed a long command starting with 
`gcc ../sysdeps/generic/glob.c -c -O2 -Wall' right before the error
messages.  Issue that command from the posix subdir of the source tree,
replacing -c with -E and the `-o /some/path/posix/glob.o' at the very
end with `-o glob.i'.  That will run the file through the preprocessor.
Edit glob.i; remove everything after the glob() function, and as much
junk as possible before it.  You need to leave in structs, typedefs,
prototypes, and variable definitions used in glob(); everything else
can go.  Then try to compile that file.  Use the same set of switches
that were used the first time, minus -I, -D, and -include options, and
add -v -Q.  It should blow up the same way; if it doesn't, you took
something out that you shouldn't have.  Mail the output and the .i
file to egcs-bugs.

If you just want to get a working system I'd stick to 2.0.7 for the
time being.  2.0.9x are alpha test releases, and may not work very
well.  There had better not be binary RPMs out there -- we don't want
people thinking they can blindly rpm -Uvh an alpha libc and have it
work.
