On which platforms is -fvisibility supported?

[Jonathan Turkanis]

Hi,

I've asked this question twice at gcc-help, but got no response.
On which platforms is the -fvisibility option supported? The GCC docs here 
(http://tinyurl.com/99wc8) suggest that it is a subset of ELF platforms. Is that 
correct?
