Resend - PATCH - Start seperating 16/32 in Ole and ole32 memlockbytes

Steven Edwards wrote:

Anywhere here is the first patch that removes a few of these imports if --disable-win16 is passed to configure. I still have a lot to go and this may need some cleanup/review from a OLE guru on Linux but it builds for me without warnings or errors under Mingw.

Changelog: Seperate Win16 and Win32 Ole support in memlockbytes.

With the right patch this time =)
