Please avoid windows.h (include everything) inclusion, find an appropriate
set of smaller include files instead, winnls.h in this case.

The test looks good to me. it passes for me under XP SP3 (32 bit), and Vista SP1
x64 (native 64-bit and emulated 32-bit modes), although in order to pass in 64-bit
mode I had to apply the following patch

-#define IS_WNDPROC_HANDLE(x) (((ULONG_PTR)(x) >> 16) == (~((ULONG_PTR)0) >> 16))
+#define IS_WNDPROC_HANDLE(x) (((ULONG_PTR)(x) >> 16) == ((~(ULONG)0) >> 16))

but that's not your fault.
