Upgrade compilation errors

[Willem Kokke]

Better late then never:

wchar_t in c++ is a separate type according to the standard. It is used for
wide chars, and in Visual Studio it is similar to an unsiged short
In fact, it is so similar, that rather them really adding a  wchar_t type,
they just typedeffed it in older version of Visual Studio

In 2003 the option got added to make the compiler standard conform regarding
this issue, and in 2005 it became the default (I think)

now if you have a library compile compiled with the old behavior, al its
function signatures will have unsigned shorts in them. ( as wxWidgets does
by default )

If you then compile the application with the standard coform behaviour, it
expects to find all function signatures with a wchar_t, since it is an
actual distinct type that does not implicitly convert
