The sparc-sun-solaris2.11 bootstrap (both multilibs) has just completed
successfully without regressions.
However, sparc/sol2.h needed an #undef to fix

Btw., I thought about running gcc.dg/compat against Studio 12.6 cc. I'd
started trying some time ago, but got distracted. At the very least, I
needed -features=extensions -DSKIP_COMPLEX_INT for a considerable part
