Current trunk can't build

[Chris Mellon]

A couple revisions ago, gdicmn.h was changed to make the operators for
wxSize, wxPoint, and a few other similar classes into overloaded
functions instead of methods (at least that appears to be it - I
didn't realize this was possible in C++, but it seems to work). The
SWIG wrappers currently in trunk, though, explicitly call
obj->operator== (or whatever) which fails to compile because the
operator is no longer overridden in the class.

Since there's been a test build since then I assume that SWIG knows
how to properly handle this, but I guess that you haven't checked in
the wrappers from that build.
