--with-wctype-functions will only work if you have configured Python
to use the Unicode variant which is used by wchar_t on your platform.

Given the warnings you are seeing, this appears to be UCS4,
so you have to add --enable-unicode=ucs4 to your configure line.

Please note that support for wctype functions is not being
actively supported in Python anymore. I'd suggest you remove
the --with-wctype-functions option altogether.
