1. win32: drop -Wno-incompatible-pointer-types when pedantic …

   27e0c3c (win32: allow building with pedantic mode enabled, 2021-09-03)
   adds -W as a workaround to the use of `void *` to hold a pointer to a
   function, punting the final solution.
   
   The type used in Windows is a generic function type, but assigning it
   from a different function interface will require a cast that was
   missing from the original implementation, so lets add that.
   
   Sadly; that is not enough, as gcc will helpfully raise a -Wcast-function-type
   warnig when casting between functions that might have incompatible
   return types (ex: GetUserNameExW returns bool which is only half the
   size of the return type from FAPROC), so create a new type that could be
   used as a completely generic function pointer, which then could be assigned
   to the correct function pointer through a cast.
   
   This has the advantage that the generic pointer functions then will be
   opaque and not useful as functions without being assigned to the right
   function pointer variable (just like `void *` was meant to be in POSIX).
