I've got no philosophical problems with submitting changes to setup.exe to
the maintainers for inclusion in the distributed program. My only interest
in all of this in the first place is to enable users to easily install
Hercules; I'm not, and have no intention of becoming, a Cygwin developer.

Hercules is built against the latest production release of Cygwin at the
time it is released. That version has changed from 1.3.10 to 1.3.19 in the
time between the last two releases of Hercules (2.16.5, released on 8 July
2002, and 2.17, released on 1 February 2003). That counts as a moving
target. In general, Hercules major releases happen every 6 to 9 months.

Cygwin does the job well enough, or else we wouldn't be having this
discussion. Were it not for inter-version incompatibilities, I'd pick a
version of the DLLs to use, keep one source tarball (and a copy of the email
saying that was sufficient to meet the demands of GPL compliance) around,
and be done with it. Unfortunately, that's not the way it has proven to
work.
