Support for C wide character strings

How about adding wchar support when calling external C/C++ routines from FTN95?

Currently compiler does auto conversion between Fortran and C character strings but today many new C routines use wide character strings. This support would simplify things and allow calling most of the DLL-routines directly from FTN95 compiler.

UTF-8 characters can be handled in the latest beta salflibc.dll. I think this has been added since the last full release.

For UTF-8, ClearWin+ converts to UNICODE and then calls the relevant API.
