Oh, and one of [my pending changes] actually (unintentially so) happens to
resolve
<https://gcc.gnu.org/PR101204> "[12 Regression] infinite recursion in
gtype-desc.c since r12-1801-g7036e9ef462fde8181bece4ac4e03f3aa27204dc",
so unless you've done any work on that, may I take over that PR?
I haven't. Thanks for offering to take it on! I'm curious to
hear how your change fixes that problem.
So, instead of my earlier drive-by fix, I've since distilled what it
actually is that is causing/fixing this (strange...) problem. OK to push
the attached "Get rid of infinite recursion for 'typedef' used with
GTY-marked 'gcc/diagnostic-spec.h:nowarn_map' [PR101204]"? (This, of
course, only fixes the symptom but not the actual underlying problem.
But I'm not going to dig deep into 'gengtype' at this time.) ;-)
Great work figuring it out! Amazing how riddled with bugs this
gengtype stuff is. Thanks a lot for the patch!
Martin
