Well packaging is easy, but IMHO not before enabling W32 Callbacks. 
Otherwise I would have proposed it by myself.

But if people want it without callbacks I could propose it.

BTW: I'd rather prefer pmoore's FFI or the C-DynaLib-0.55, which work 
like a charm with w32 and cdecl callbacks and don't use such a horrible 
and MSVC-only aldo-style hack.
Or any other libffi or ffcall based FFI solution, which can be used for 
Win32::API callbacks.
