.hidden itself is indeed ELF specific (and was initially invented by Sun
IIRC), but libgcc already has provisions to handle similar concepts on
other targets (cf. asm_hidden_op in configure.ac and the .vis files). I
haven't yet studied how this applies to Darwin (which supports
.private_extern instead).

As I said: I believe they are correct in principle, non-Unix targets
being ELF and using gas, so you're probably safe. I guess the x86
maintainers will tell (or enraged target maintainers when they see
bootstrap failures ;-)
