Chasing this through gcc -E reveals it comes down to this statement: sc_ = (struct sigcontext *) &uc_->uc_mcontext; I believe uc is of the offending incomplete type: struct ucontext uc. If I manually ebuild prepare ${ebuild}; cd ${workdir}; and replace the two occurrences of "struct ucontext" with "struct ucontext_t" in gcc/config/i386/linux64.h; ebuild compile ${ebuild} now succeeds. However it's not at all clear to me when this fix is applicable and when, not, so this workaround is at best a possible fix. I suspect this is something to do with fixincludes and the correct magic sauce could be backported from newer gccs. Good lord, what a nightmare it must be for toolchain people to maintain this thing...
