OK, here's a new attempt, this time leaving the hppa bits in. The
main tricksy bit is where s_lock.h is simplified a bit by moving the
fully inline GCC-only hppa support up a bit (it was handled a bit
weirdly with some #undef jiggery-pokery before to share stuff between
aCC and GCC), making the diff a little hard to follow. Does this make
sense? It might also be possible to drop one of __hppa and __hppa__
where they are both tested (not clear to me if that is an aCC/GCC
thing). I have no idea if this'll actually work (or ever worked) on
NetBSD/hppa... if it comes to it I could try to boot it under
qemu-system-hppa if that's what it takes, but it may be easy for you
to test...
