Grumble.
Yes, I know. It's the reason why I never got around to submit the few
changes we made locally. Our GCC has some local changes that make the
unwind descriptor more compatible between the two models. I am still
asking the details to the hppa specialist at AdaCore, but it seems
that starting with GCC 3.4, the frame was setup in a more compatible
way already. If you're interested, I'll let you know the details of
our implementation.
