Sorry, yeah, because Mono's linker script is actually specifying
the version of the symbols:

http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gnu-linker/version.html

It doesn't deal with the visibility of the symbols. This is
achieved with the GCC visibility attribute.

Still, WAPI is public and Mac OS X ld '-unexported_symbols_list'
can't be used.

I'll send you a patch that renames the symbols later tonight.
