Well, you don't need, but copyright assignment is automatical in most 
cases, so you do have copyright for your own work, wanted or not (see 
later text).. =)

Well, since cygwin is GPL licensed you can change how ever you fit in 
your purpose as long as you publish sources.

But for Cygwin community it's better to use "official" channels to 
maintain changes etc. There is FAQ and docs about that in Cygwin site.

Well you can distribute cygwin1.dll and sources for it or point out 
users to install Cygwin.

Now you got it wrong. Copyright is something that you "can't buy", 
copyright is property for something you create and you own copyright to 
your work, exclusively without any special assignment. If you're working 
for a company in most cases programs that you create at your work time 
are copyrighted by that company, nyt by you as individual. But on the 
other times, copyright is owned by you.

GPL in turn is a license, a contract, an agreement that how you can use 
that particular piece of work. One of essential parts of GPL is to 
permit others to modify and pass those modifications further, but they 
have to publish their modifications.

Long list that I can't see how they're related to copyright or licensing.

BTW, have you ever tried to run Windoze + Cygwin and Linux 
simultaenously. Works great.
