The LGPL enables you to link an open source library to an closed source
project. Since you won't be using any LGPL code, this is not an issue at
all. There is no reason at all to release your own code under the LGPL.
The LGPL is just a completely other issue than using GPL'ed programs from a
commercial application.

Well, I don't think you need a commercial license. You don't link
anything
with GPL code. You don't modify any GPL code (and if you did, you could
still supply the source). Just like it's legal to sell Linux for big
bucks,
you can sell Cygwin at any cost you like.
Generally, whats not allowed, is linking non-open-source code with GPL
code.
However, this isn't a matter of source code at all.
Now a commercial application using binaries compiled from GPL source:
that's
very common. Many, many softwarehouses develop using GCC and sell
closed-source software. Many commercial websites run Linux/Apache/MySQL.
Non
problem at all.
