(I'm sure i'll be corrected if i'm wrong here.. :)

The issue is simply:
 - if you distribute on cdrom, include the cywin sources (no problem,
 - if you distribute on floppy, include the cywin sources (aargh!)
 - if you distribute via http/ftp, place the cygwin sources on the same
   permitting users who _chose_ to do so to get the relevant sources.

You could make it awkward by splitting the files into 1MB lumps and use
some strange compression-format, if you wanted to discourage unnecessary

You _don't_ have to wrap _all_ the sources up in the same archive. They
can be separately-downloadable files.

I'm not aware of any separate source archive which produces _only_ the
dll and not
the tools; such an archive, if you created it, would both fulfil GPL
and be easier to fit on some floppies.
FWIW, the cdk/src/winsup directory - i.e. the sources for the cygwin dll
zip into about 700 kb. (one floppy disk!)

Now, which bit don't you understand ? 8)
