OK.

I will post different patches for the 3.4 branch and HEAD.  Hopefully
you correct this soon since for *-rtems to compile Ada, the
pthread_key_t type definition has to change with the current state of
the world.

If you are going to take a while, I could commit that change on the
head and then back it off when you get your work done.  How does
that sound?
