I was having problems with 2.4 so I'm now back to using a recent snapshot.

I patched configure to check for a snapshot version number and replace it with
2.16.99.9 if it finds it.

Did you build a final glibc with the final compiler? I was missing unwind
symbols: _aeabi_unwind_cpp_pr0 etc, maybe one of the patches fixed this? Maybe
it only happens with iWMMXt? I added the symbols to LIB1ASMFUNCS in
arm/t-bpapi, I do not know if that is the appropriate file, maybe someone can
advise?

Anyway, congratulations!
