Go read the GPL; you only need to provide sources to people who 
_ask_for_them_.  These days, you could probably just refer them to a web 
page or something.  Also, they have to make any _changes_ they've made to 
the source available.

Including GPL'd code in a project as a shared library/DLL is just peachy; 
GPL requires the end-user to be able to replace/upgrade the GPL'd hunk 
without intervention.

I went through all this nonsense (IMHO) when I built a binary Python 
distribution for BeOS way back when... I wanted to include readline support, 
but libreadline is GPL'd.

So contact their tech support and tell them you want the code for 
cygwin1.dll, gzip, tar, plus any changes they've made to the code...

Hope I wasn't sounding too snippy in this message, I've actually had to 
explain this several times this week.  Must be related to the change in 
seasons. ;-)
