Corinna's original message had set the Reply-To to the cygwin mailing
list.  My message didn't do that but you replied to the list anyway.
Hmm.

Ok.  You're providing some sources but not all.  That's a little
mystifying to me.  I don't know why you chose to provide sources for
wget, pdftohtml, etc.  but not for the cygwin DLL, tar, gzip, bzip2, or
unzip.

How you are not complying is that you are apparently not providing the
source code for the DLL and other random binaries.  I'm not sure how
this was unclear from my original message.  Are you saying that you have
the source code available for such things as the cygwin dll and tar and
that if someone asks you'll provide it?  If so, I think you probably
should make that clear on your web site.

I'm only asking that you make available the cygwin DLL sources and any
other GPLed sources that you are using.  The cygwin sources are 3878779
bytes.  The tar sources are 967054 bytes.  The other packages (with the
possible exception of perl) are not that large either.

Let me restate it:  You can't rely on the fact that the source code
is "freely available".  As I mentioned, that won't be the case for long
with cygwin 1.3.10.

My suggestion would be to just make the source code available and
include a line that says "Please don't use this.  It is just here for
GPL compliance." or something like that.
