There's the usual misconception about the GPL.  If you create an
application which is linked against the Cygwin DLL (or any other GPLed
library), but you only use the application in-house, there's no reason
at all to distribute the source code to your collegues.  If one of them
really wants it, he can always ask you, right?  Only if you provide the
binaries to customers or to the world in some way, you are supposed to
provide the sources codes as well in a GPL-compatible way.
