Can I suggest you install cygport, and look at using it, to more easily build Cygwin packages, if there is any kind of common infrastructure used, even just configure && make, autotools, and many other builders, rather than DIY. Once you understand the cygport approach, it helps eliminate a lot of the mismatches doing builds between Cygwin and other Unix platforms, and makes overriding parts of the process and applying or creating patches easier. You can often just apt-get source /package/, get the source .tar.gz out using ar and tar, create a .cygport script, and build. For Debian, GNU, and other popular distro mirrors, cygport can get the source packages directly from their mirrors. -- Take care.
