Hm yeah - I guess it was more a response to Reimar - I'd go as far as to
say we should consider x32 as msvc, i.e. "if msvc builds are degenerate
compared to gcc builds, don't allow it by default"; likewise here (compared
to x86-64 or x86-32).

(And yes I know msvc has on gcc-inline-asm support so it is kinda
degenerate...)
