In general, anything that takes a char* argument (or any structure
containing a char*) exists in two forms - a FunctionA() and a
FunctionW(), with the latter being the 'unicode' (16-bit wide char)
version. There is then a macro defined that maps Function onto FunctionA
or FunctionW as appropriate.

Since those macros are of the form

  #define Function FunctionA

then prefixing with :: causes the scope specification to apply to the
result of the macro, and it doesn't cause a problem.
