This is getting absolutely ridiculous, but I pushed another "fix" to
staging (basically, I now have to cast a member function pointer to its
own type before comparing it with another member function pointer cast
to its type).

With regard to upgrading gcc versions, I think that the latest 4.8
version of gcc should be a reasonably safe bet.  However, I don't know
whether darwin-ppc is still a supported platform for it.  One would
probably have to take the last supported version.
