Hello,
We are developing a commercial application involving a database.
The database we want to use is Postgres and the target platform is at
present Windows NT. In order to compile Postgres we need Cygwin.
From my reading of the FAQ my understanding is that because Postgres is
"free" we are entitled to use Cygwin as "free" software. Is this correct?

If you are developing a commercial application using GPLed software
you will undoubtedly have to provide sources for your application or
you will be in violation of the GPL.
If you have specific questions about cygwin, send mail to info@cygnus.com.

This is generally true but we have changed the license recently. The
new license will be in B21. The change allows you to link libcygwin.a
into your software and redistribute it as long as *your* software sources
are made freely available. It does not allow you to use libcygwin.a for
proprietary commercial software. For that you need to contact Cygnus for
a commercial license.
I've included the CYGWIN_LICENSE file from recent snapshots below.

Are you sure about this?
Using GPLed software to compile a commercial product doesn't imply that
the final product needs to be under the GPL. Infact the new versions of
the GPL & LGPL have new clauses to try to get round this confusion.
I have stuff covered by both the GPL & LGPL, and I get questions asked
about inclusion into commercial products. I keep stating that the reason
I used (in this instance) the LGPL is that only the library, not the
final product is covered.
PS: PostgreSQL itself is covered by the BSD licence.

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.

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.
