Why your version not working was described in at least two letters.
There is one (yet) unsupported solution for your problem. I've written 
pre-processor for Pyrex.
You can download it here:

It's not yet accepted or rejected by Greg (I've sent him a patch but he 
possibly has no time to check it out).
Using it you can rewrite you code as:

def map_win32(self, err):
    #@if defined(_windows)
    return _wgpr._builtins._map_win32(err)
    #@endif

At symbol (@) used to distinguish normal Python comments from 
conditional compilation statements. For more details lookup:
