The major changes are using 32 bit unicode values internally and
implementing collating symbols and equivalence class expressions.

I'm looking into that. First thing, your testsuite uncovered a bug in
the latest fnmatch in the C locale. Comparing pointers instead of
comparing characters was never a good idea for pattern matching...
When I'm done I hope that our 3.5 fnmatch won't be overridden by the
gnulib version :}

No worries, thanks for the testcases, I think I have some result
tomorrow.
