It *also* means that depending on unknown third parties is asking for
trouble.

AFAIK Windows binaries are distributed from the GNU servers just because
someone volunteers to do the job, not because it is a requisite for the
release. So it should be up to those volunteers to decide if they want
to include those libraries (GnuTLS, image support, etc) on the binary
package.

And if someone volunteers for maintaining a system that updates those
libraries, it is the job he picked.

A slightly different issue is to decide if changes to Emacs sources are
allowed to do that chore on certain way, but then it is up to the
volunteers again and solid reasons should be given to reject those
contributions.

IIRC Lennart also distributes an unpatched Emacs.

Ah, yes, the Emacs w32 people. Now I understand your stance better (and
maybe Eli's). I think it would be unfair and unreasonable to make you
responsible of doing the job related to those libraries, but I also
think that you are not obliged in any way to provide binaries of
anything. Keeping the sources on a ready state is enough, thank
you. (Not saying that you are *obliged* to do that either.)
