That's 0709b7ee72e4bc71ad07b7120acd117265ab51d0.
Not too surprising that it broke and wasn't noticed without access to
hppa - the hppa code uses gcc inline assembly outside of the big
defined(__GNUC__) and inside the section headed "Platforms that use
non-gcc inline assembly".

I think it's easiest solved by moving the gcc inline assembly up to the
rest of the gcc inline assembly. That'll require duplicating a couple
lines, but seems easier to understand nonetheless. Not pretty.
Given you got the error above, you used gcc. Have you used non-gcc
compiler on hppa recently? I seem to recall you mentioning that that
doesn't work sanely anymore? If so, perhaps we can just remove the !gcc
variant?
