cannot initialize WNDCLASSW, WNDCLASSEX, WNDCLASSEXW window structs

[Phil Lavoie]

Just to clarify:
xxxA = Ascii;
xxxW = Wide chars (UCS-2);

And because I forgot to mention, to mimic the preprocessor 
directive, the bindings use a version conditional compilation. 
Therefore, you use it like that:
rdmd -I/where/you/put/the/bindings -version=Unicode yourmodule.d

You can double check in the code, but IIRC, only the first letter 
is capsed.
