It's not just a matter of using GPL'd software to build the commercial
product. The cygwin runtime support code is GPL'd. Software which uses that
code at run-time must also be GPL'd. This is the principal difference
between the LGPL and the GPL. Suppose the runtime is a shared library. If
it's covered by the GPL, a user of that library is "infected" with the GPL
as well. If it's covered instead by the LGPL, the user of the library is
*not* infected.
