ELF has a wider notion of visibilty that dllimport/dllexport; the latter
is pretty well mapped on to a subset of the ELF notion. I don't really
see an advantage to trying to do anything with DECL_VISIBILITY on, say,
PE/COFF, but there may have been enhancements to that format since I
looked last.
In short, I think not, but I could be wrong.
