Great! Why didn't you just make a patch and submit it?

Well, as Alexandre already has pointed out, Win16 should be
mostly implemented by using Win32. I agree with him that use
of the 16-bit code should be eliminated as much as possible.
Moreover, until now I just have replaced only obvious places:
16-bit functions which just thunk up to win32 without any

I'm not going to blindly replace 16-bit calls by 32-bit.
I look into the code and do think twice before submitting
Anyway, thanks for your comments.
