How do I apply patch files to my LilyPond binary on Windows?

[Robert Murdoch]

Hi,

I was wondering if it was possible to apply patch files to binaries on 
Windows, and if so how to do it.

I have been waiting for about a month for LilyPond 2.19.81 where 
hopefully the problem with the repeat ties in chords will be fixed (in 
case any reader doesn't know, as of 2.19.80 repeat ties can be applied 
to all notes in a chord, but not individual notes). I have been eyeing 
the bug tracker (https://sourceforge.net/p/testlilyissues/issues/) and 
git repository (http://git.savannah.gnu.org/cgit/lilypond.git) and it 
appears to have been fixed in the master branch.

Now I'm wondering if I can apply the patch at 
https://codereview.appspot.com/332990043 to my Windows binary file. I 
was going to complain that I was running out of patience waiting for the 
next unstable release, but then I realised it's my own fault for not 
asking this question sooner.

Anyway, thanks for reading.
