I didn't write this.  Please be careful with attributions.

Nothing in cygwin.dll is under the LGPL.  If it were, no one would
have to pay Cygnus in order to use it commericially.

You (and Fergus Henderson, who said something similar) are right,
I misstated it.  Cygnus distributes their code under the GPL,
which "infects" anyone using it, requiring them to distribute
their own sources.  Cygnus can also issue their code under a
a restrictive copyright that would only allow licensees to use it
but would not "infect" them.  What Cygnus must not do (if they want to
make any money off this) is to release it under the LGPL or any other
copyright that allows unrestricted redistribution.

It will be interesting to see if Cygnus can actually develop a market
for it.  I think that, in order to do so, they will have to greatly
improve its quality, which would be of benefit to people making
non-commerical use of it under the GPL (to the degree that the GPL'ed
version shaes code with the non-GPL'ed version).  OTOH, I plan to put
any patches I submit under the GPL, which would prevent Cygnus from
distributing them under their restrictive license.  This will have
the downside of not having these patches included into the Cygnus
distribution, but if that's the price I have to pay to keep them
free, so be it.
