Meanwhile I found the cause of the problem. wchar_t is mapped to unsigned
short by default when using MSVC7.

To solve the problem, use the compiler flag /Zc:wchar_t. This makes wchar_t
a type of its own, independent of unsigned short.
So the template specialization for wchar_t is not used and the above code
compiles.

Best regards, Peter.
