Since I use Emacs for a lot of strange things on Windows and not only GNU/Linux I would love to help testing and iron out bugs. Is there someone building Emacs binaries for Windows on a regular basis?
 
Thanks to those who have replied about precompiled Windows binaries. 

To help others find them more easily I have added a section about this on the pretest page in EmacsWiki:
