Here is the index.txt file from
ftp://belgarion.resnet.gatech.edu/pub/cygwin/B20/cygwin-sources/

*****************
This directory contains the minimum cygwin sourcecode to comply with the
GPL. Since executables with dll's are considered a single program, and
since the cygwin dll is under the GPL, if I want to distribute compiled
applications that use the cygwin dll, I am required to place my
application under the GPL. In order to comply with this, not only do I
have to provide the sources to my application, but also I must provide
the sources for the cygwin dll that I used.

Now, I don't really expect anyone to download this stuff - it's much
easier to get the full sources for the entire cygwin *environment*
directly from Cygnus (http://sourceware.cygnus.com/cygwin) rather than
just the sources for the cygwin dll and its immediate dependencies which
I provide here. In addition, if you go to the Cygnus website, you can get
a nicely packaged, precompiled version of the entire cygwin
*environment*, which includes lots of nice extras.

winsup.tar.bz2           original cygwin sourcecode
winsup-coolview.tar.bz2  winsup sources, modified using Sergey's patches
*****************

Since I built the binaries on my ftp server using the coolview
(post-20.1) dll, does this directory satisfy the requirements of the GPL
wrt cygwin-based programs (provided I also supply the source for the
specific programs, of course) ?
