This doesn't work for CGIs on Win32, but then neither does -T in the #! line.

Actually -T works perfectly fine on Windows with Apache. As I discovered with IIS you have to hard code it else where.... Taint with Perl on NT/IIS.

On Windows if you run IIS then the shebang is ignored, so you don't need it, and Apache can either follow the shebang (default) or use the Registry like IIS does.
