Thanks Robin.  I managed to get a bit further by omitting unicode from the 
build.  Now however, I'm getting a link error:

build\temp.win32-2.5\Release\src/helpers.obj : fatal error LNK1112: module 
machine type 'X86' conflicts with target machine type 'x64'
error: command 'link.exe' failed with exit status 1112

So I assume that the wx helpers.obj file is a 32-bit file.  Then I try to re-
compile helpers.cpp and get the overload errors again:

C:\wxPythonSrc\wxPython-src-2.8.7.1\wxPython\src>cl.exe /EHsc helpers.cpp
Microsoft (R) C/C++ Optimizing Compiler Version 14.00.50727.762 for x64

helpers.cpp
C:\wxPythonSrc\wxPython-src-2.8.7.1\include\wx/filename.h(393) : error 
C2666: 'wxString::operator []' : 3 overloads have similar conversions
        C:\wxPythonSrc\wxPython-src-2.8.7.1\include\wx/string.h(824): could 
be 'wxChar &wxString::operator [](wxStringBase::size_type)'
        C:\wxPythonSrc\wxPython-src-2.8.7.1\include\wx/string.h(822): 
or 'wxChar &wxString::operator [](int)'
        or 'built-in C++ operator[(wxChar, unsigned int)'
        while trying to match the argument list '(wxString, unsigned int)'

Do you or does anyone know how to correct this problem via a compiler switch 
or setting to ignore overload errors?

Thanks
