I *think* it's new in gcc 4.0.  But considering that nothing
catastrophic happens if those symbols get actually exported,
there's not much harm in moving to this scheme completely.  The
sintax is as simple as:

#pragma GCC visibility push(hidden)


One very wrong thing about info and web pages of gcc, glibc,
autotools, etc is that they don't mention when a feature was
added.  Gtk+ has got this right.  Would be nice to have that in
Cairo too.
