Well, no it is not GNU Pro.  It is PGI.  They do redistribute the
bundled cygwin.dll, I believe under a license agreement.  PGi also
recently signed a deal with Interix (formerly known as OpenNT) to make
their compilers compatible with Interix.  However to get PGI you pay a
lesser amount of appropriate cash compare to GNU Pro.  Beside, their
compilers are known to be of high quality commercial compilers.  You do
not get ligcygwin.a.  If you need that you will need to license GNU Pro
from Cygnus.  But you do get cygwin.dl and their version of dlltools.
So the question is I am licensing cygwin.dll from another vendor,
without libcygwin.a.  This vendor supplies the dlltools too, should I be
violating a GPL if I extract the export codes from cygwin.dll using the
licensed cygwin.dll.

I am just curious here.
