I tried it on hppa64-hp-hpux11.11. The gomp support mostly works on this
target.
I didn't see any regressions but asynchronous_9 fails:
FAIL: libgomp.fortran/asynchronous_9.f90 -O execution test
on Solaris, this is due to the test's stack usage, which exeeds the 8 MB
default. Maybe the same problem on HP-UX?
Yes.
