So apparently Fergus found the solution.

BUT, a last question springs to mind (And I really hope that this will
be the last one as I have the impression that this list is quickly
turning into a mailing list of lawyers)

Given that the executables produced by linking with the GNAT's libcygwin
are free of GLP code it remains the problem of distributing and using
cygwin.dll.
Can I distribute it into the same package (say the same tar archive)
with my proprietary software ?
And even if I don't, do my clients (commercial clients) have the right
to download it themselves and use if for commercial purposes without
paying a fee ?
