I don't think it will ever be fixed for GCC 3.3 / Mac OS X 10.3 ?

In the meantime I'm adding a small note to gdcmac that templates
needs Mac OS X 10.4 / GCC4 to work and aren't supported fully for
Mac OS X 10.2/10.3 and that this will break readf/DMDScript/etc.

But if someone has a patch to enable "link once" for GCC 3.3.6
on Darwin, I would be happy to apply it to the gdcmac 0.20 build.
(i.e. the same way that I ported .framework support over earlier)
