First, let me say that I have no intention of maintaining lilypond - I 
am aware that even replying to this e-mail puts me in danger of 
acquiring another couple of packages ;-) I absolutely love lilypond and 
would like it to stay within Cygwin if at all possible, but I don't have 
the time right now to take on a package that is going to be a little 
problematic.

I had a go at building lilypond for x86_64 about 18 months ago, but 
didn't get very far. I managed to produce an executable, but 'make doc' 
and 'make check' both failed, so I didn't have any confidence in the 
binary produced. My need for a working lilypond exceeded the tinkering 
time available, so I just used Fedora.

I've tidied up the cygport file this evening, and this (along with a 
small patch) is attached. Hopefully this will be a starting point for a 
prospective maintainer with the time to do it justice.

Dave.
