[perl-win32-gui] Patch for 0.0.340 on Threaded Perl 5.005.03

[Garrett Goebel]

This attached patch includes all 3 of Paul Moores patchs and one of my
own which fixes build 340 for compilation under threaded perl 5.005.03
and adds in 2 additional events and one method: 

BN_PUSHED, 
BN_UNPUSHED, 
GetDlgItem

I made the diff using Cygwin's diff. If there is a better utility to
use, let me know.

If anyone is interested in binaries, email me.
