Exposing gthreads, and making exceptions safe under cthreads

Actually, I suppose that if the above POSIX threads subset was in a
library that was linked with last, if the user had their own POSIX
threads library everything (including libgcc) would use that for
preference.

So, I guess I'm okay with having a POSIX-threads-subset library instead
of a gthreads library after all.
