Ok, I'll do that this weekend.

This is supposed to be like wxWidgets/include/wx/msw/setup0.h where
you select what you want included with your wxLua bindings build. I
will change it to wxluasetup.h this weekend.

These should all be defined! I'll get a new cvs head checkout at home
in linux (mine is probably a month old)  and see if I get them. The
wxLUA_USE_XXX are certainly defined in luasetup.h though.

     !%wxchkver27 void SetConfig(wxConfigBase *config =3D NULL)

Again, I'll do a wxWidgets cvs update and see if I get the same errors
and fix them.

There was no log attached, could you resend it?
