Interesting, I don't see that here.

I have a vague idea that it was once important to say "register" if
you are going to use the variable in an asm snippet that requires it
to be in a register.  That might be wrong, or it might be obsolete
even if once true.  We could try taking these out and seeing if the
buildfarm complains.  (If so, maybe -Wno-register would help?)
