Yes, I know.  That was my starting point.

There are two things:

1. I don't think __prepemacs should be called for this package because 
the compile process explicitly byte compiles most of the *.el files. 
There are three (at the top level of /usr/share/emacs/site-lisp) that it 
does not byte compile.  I don't know the reason, but I don't think the 
Cygwin build should override this upstream decision.

2. I would prefer that __prep_texlive not be called, since it causes the 
postinstall script to do unnecessary work.  All that's needed for auctex 
is mktexlsr.

I'm attaching my .cygport and .cygwin.patch files so you can see how I 
dealt with this (after changing src_postinst.cygpart so that I could 
redefine __src_postinst).
