The first problem with wchar.h is that it's missing the stuff
needed for C++ compatible headers, either:
-------
#ifdef  __cplusplus
extern "C" {
#endif
...
#ifdef  __cplusplus
}
#endif
-------
(wctype.h has them.)

Or maybe:
-------
__BEGIN_DECLS
...
__END_DECLS
-------

Is this a C or C++ function?
