Right and remember that "Cygwin tools" includes source code for the cygwin DLL and any other DLLs that are required to run the tools. This is basic GPL and it makes me wonder how you could have missed this if you did the research that you claim to have done. You provide source code to any binaries that you distribute. It's pretty simple.
