IIUIC, the visibility attribute is only relevant to ELF targets, which
cygwin is not. Hence the warnings, while seemingly redundant, are at least
accurate[*]. The visibility attribute needs wrapped in a macro that can be
undef'd on non-ELF systems.

If you can produce once that shows excess warnings being emitted, yes, that
would be worth filing a PR. Hmm, a quick test I couldn't get excess ones, but
the line numbers all look wrong..
[*] - and without seeing the actual code I don't even know that there aren't
that many attributed decls on the same line...
Can't think of a witty .sigline today....
