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.
I havent contacted them about this as i could be in error and havent at
the moment got time for an exaustive search of their site, but i thought
i'd best let the list know.
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. ;-)
