64-bit DWT & Windows static libs

[Mike via Digitalmars-d]

I'm investigating what it will take to port DWT to 64-bit.  For 
Windows, it looks like I will need 64-bit versions of the static 
libs here: 
https://github.com/d-widget-toolkit/org.eclipse.swt.win32.win32.x86/tree/master/lib 
(ole32.lib, msimg32.lib, etc...)

I have several different versions of these files on my computer, 
but does anyone know what the true source of these files is.  Is 
there a re-distributable or runtime from Microsoft that has these 
files?

Thanks for the help?

Mike
