You can distribute the DLL as long as you are willing to make source code
for the DLL and for your program available.

Unfortunately, use of the cygwin DLL by your program means that your program
is also subject to the GPL.  That means that you must provide source code for
both your program and the DLL if someone asks for it.

Cygnus does offer other licensing arrangements which allow you to avoid the
source code restriction but you'll have to pay for them.

So, I think this is good news for you since you are going to be distributing
a GPL program.
