The problem with -export-symbols is that, as I understand it, it does some
weird symbol hiding thing that doesn't actually support symbol versioning
and you can't use it to do that because it doesn't use the same linker
option.  But I could be wrong and would need to experiment with it.

Not so far as I know.

Unfortunately, they use different options depending on whether you're
using GNU ld or Solaris ld on Solaris, IIRC.  But otherwise, yes.  And I
don't remember what happens on Mac OS X, which uses the GNU toolchain but
does its own weird thing with shared libraries that isn't ELF.
