I replied to this to Corinna, but as I got an error message from the
list server I had no idea who got it or not.
So I've forwarded the bounced message - see below.

We have the source code to wget, pdftohtml, etc available for download
as part of the "source code" download link that is on the website
I referenced. Some of these packages have been very slightly modified (mostly
Makefiles). As I said, our project is all GPL and GPL-compatible
We use the cygwin dll as downloaded from a cygwin mirror. So you want
us to mirror the whole cygwin source code as well, in New Zealand,
where we have to pay data charges for international traffic in both
directions? The GPL says that if someone we give binaries
to asks us for the source code, we are obliged to do so. I don't
see how we're not complying...

Our software is all GPL or compatible. We use an unmodified version
of cygwin, so the source code of the library we distribute is already
publicly available. We have sources for the 3rd-party packages mirrored
for download as well.

OK, thanks for that. Is there any other way to set the root directory
for use by cygwin1.dll (eg CYGWIN environment variable) other than
the windows registry entries used by a proper cygwin install?
