Are you sure that the unicode flags were turned on for both builds?
What where the other 4 unresolved symbols mentioned in the error message?

Does s:\temp\wxPython-src-2.8.12.1\lib\vc_dll\mswuh exist? That is
where it should be finding wx/setup.h. If that folder doesn't exist
then you probably didn't actually make the unicode build of wxWidgets.
(The 'u' in the folder name is for unicode.)
