Oops, I didn't see that. I'm glad to see this is looking so simple :-)
Actually, I don't think we should the same flag name for this, since "hidden"
is an ELF concept, not a COFF one, just that we should match the behaviour of
the flag.
Hmm, or do people use -fvisibility-inlines-hidden on MinGW or something? Where
does the hidden-dllimport.cpp file come from?
Also, is it the case that -fvisibility-inlines-hidden just ignores the problem
of static local variables? If that's the case we can probably do it too, we
just have to be sure, and document it eventually.
