64-bit wxPython Compile errors

[Dave Burdick]

I've managed to compile the wx DLL's in 64-bit, but I'm having trouble 
compiling the rest of it (i.e. the Python extension .PYD files).  It's bombing 
when I run the setup.py command:

C:\Python25\python.exe setup.py build_ext --inplace MONOLITHIC=0

Here's the dump:

C:\wxPythonSrc\wxPython-src-2.8.7.1\wxPython>C:\Python25\python.exe setup.py bui

I'm using a 64-bit version of Python 2.5.1 (the standard 64-bit Windows 
download from Python) using the VC8 SDK compiler.  Could it be that there are 
incompatiblities beween the VC8 compiler and the VC7.1 compiler which was used 
to compile Python 2.5.1 that could be causing the problem?
