When
 I execute those examples, I get them both to plot with the different 
rules, no matter if backend=0 or backend=2. I did find out though, that 
the internal wxDC::DrawPolygon function has WXUNUSED_IN_WINCE(fillstyle)
 defined. Thus, if you're having a system
where WXUNUSED_IN_WINCE is defined as WXUNUSED (for WinCE builds: #ifdef
 __WXWINCE__), then the fillstyle is completely ignored (thus I think it
 uses the only fillstyle available in WinCE).





Did you mean wxDC instead of wxGC? Because in the wxwidgets source I 
can't find any wxGC, only wxDC (the only thing I find is :"#define 
wxGCDC wxDC")
