special cases and other things in wxPython, and since I plan on making several more, I've decided to put the SWIG sources in wxPython's CVS instead of relying on maintaining patches. This effectivly becomes a fork of an obsolete version of SWIG, :-( but since SWIG 1.3 still doesn't have some things I rely on in 1.1, not to mention that my custom patches would all have to be redone, I felt that this is the easier road to take. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@15307 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
