[PATCH v2 0/3] MR8411: Draft: More fixes to CallWindowProc[AW] calls storing the return value in a 4-byte type.

[Bernhard Übelacker (＠bernhardu)]

While preparing !8397 I wondered If there other uses of CallWindowProc[AW] which use a 4-byte sized type to store the return value, while at x86_64 LRESULT is 8 bytes.

  v2: winetest: Use LRESULT to return value from CallWindowProcA.
