I've just installed the most recent version of emacs+emacsw32 (Emacs-22-CvsP070116-EmacsW32-1.34.exe), but there's something going wrong when I want to customize it.
When I go to Options -> Customize EmacsW32 and click on "Set all to w32 style!", the following warning messages appear:
Warning (w32shell): When using 'cmd' program 'patch' can't be found Warning (emacsw32): Can not save to file because custome-file is nil
Oh, and for some odd reason this also maximizes my window...
After looking at the 1.14 patch notes on the site, I think the problem comes from the fact that I simply do not have a patch.exe in my C:\Program Files\Emacs\EmacsW32\gnuwin32\bin folder. Perhaps a simple packaging error?
