Actually, I'm pretty sure it works on Darwin: http://tinyurl.com/lsnxf (it's 
Apple documentation, would that be enough for Mach-O? :) )
By the way, if GNU emacs can be considered an Operating System, binutils are 
still sane enough not to be considered one.
And finally, Intel ICC compiler supports visibility too, so it's not just a 
GNU thing.

I can read enough to see that a.out can barely be considered an executable 
format for modern operating systems, that PE copes with requirements 
completely different from the ones of the modern unices, and that Mach-O, 
well, has its black spots, especially when concerning security.

And is more reliable whn a dependency is removed and when an ABI is broken.
The fact that shared libraries are slower than statically linked code does not 
mean that one has to avoid using the features that allows to improve their 
performances.

It's FFmpeg project that gets a bad security reputation, so, well, too bad for 
you, considering it's a pretty simple thing that is required to avoid such a 
reputation :)

As Luca already noted, if you were looking for a GNU zealot, you passed right 
over my head. The visibility attributes work for both ELF and Mach-O, they 
work on GNU/Linux, uclibc/Linux, on FreeBSD, on OpenBSD, on Darwin, ..
And about portability, that is always one of my main concerns; the patches I'm 
sending are not hindering anything. The only thing is that they don't enable 
visibility on ICC 9, but that's just because I don't have it at hand to test 
it...

Uoti's reply already covered this.

Cya (sure that there are at least some FFmpeg-using projects that would 
benefit from a bit more open mindset)
