Postgres, WinNT and CygWin Licensing

BigJocker asks: "Im developing a program under Linux which connects to PostgreSQL. I want to port the software to WinNT, but i have read in the documentation that to make Postgres run on WinNT you have to use CygWin, which has a very particular license, is free if you distribute your code. If i want to sell my software (which is code-independant with PostgreSQL) for the WinNT OS, i have to compile Postgres with CygWin, and distribute the binaries along with the source code, so i keep the GPL license, but my software is distributed in binary form with a license from myself. Then, how do i distribute it? is there a way to do this? has anyone tried it? is it even legal? "
