Right. I am still testing with gcc on HP-PA. I'd kind of like to
keep it running just as an edge case for our spinlock support, but
I'm not sure that I want to do any huge amount of work on meson
to keep that going.

I do have a functioning OpenBSD installation on that machine, so
one alternative if the porting costs look too high is to replace
gaur with an OpenBSD animal. However, last I checked, OpenBSD
was about half the speed of HPUX on that hardware, so I'm not
real eager to go that way. gaur's already about the slowest
animal in the farm :-(

If you've got an idea where to look, I could add that to my
to-do queue.

In any case, I don't think we need to consider HPUX as a blocker
for the meson approach. The value-add from keeping gaur going
probably isn't terribly much. I'm more concerned about the
effort involved in getting meson going on some other old animals,
such as prairiedog.
