Thanks! I hope libwin32@ users (in CC) can help testing these
changes. I know there's a lot of users who have been
experiencing random crashes using callbacks and/or x64.

For libwin32 users: the archive is marked with v0.65:

I'm afraid you're much more skilled in Win32 development
than I am. I'm mainly trying to be a good maintainer
to keep the project alive for the good of Win32 Perl users.

Thanks to you again.

I'll mention this patches to libwin32@perl.org and
collect some feedback, and then roll a new version out.
