Maybe...

I seem to recall that Redhat 9 & Fedora may be using UCS-4 by default. 
Have no idea about other Linux distros.

I would also think that there's something wrong with the configure tests 
that lead to the HAVE_USABLE_WCHAR_T symbol - I'm quite surprised that 
Thomas is not finding this defined on his Linux systems, and I'll try 
and check my FreeBSD systems over the weekend.

I would have thought that trying to use unicode from ctypes without a 
clear idea of the platform/python unicode status would be akin to Russian 
roulette...
