I've cc'd upstream = John Cremona, in case he wants to comment.

This is only currently needed on Cygwin. It will never be needed for
Debian. Don't bother with it for Debian.

I think we only include f2c because of Scipy.

When we included this in Sage, FLINT didn't exist. I've cc'd Bill
Hart in case he wants to comment (again) about this.
I think the upshot is that FlintQS should be removed as a separate
package, though this could require substantial work
due to how Sage uses qsieve. I'm not sure.

I think we only ship it since we need it in order to get GNUTLS, which
we only need
in order to provide a secure SSL mode for the Sage notebook. One
could also just use
openssl and completely get rid of the whole GNUTLS if Debian ships it
as a system library
and somehow dances around the non-GPL-compatible nature of OpenSSL.
Making it easy to
switch from GNUTLS to openssl for the Sage notebook would require a
tiny amount of work by
a notebook developers.
