If it is a compile time option that actually links stuff (and the
headers suggest that), we should add something like

This version of LilyPond has been compiled and linked with a version
of Ghostscript licensed under the AGPL.

to the --license text.  The implications are then for the user to find
out.
We should also add this to the license information in the documentation
(namely that --license should give you the information whether there is
the Ghostscript API linked in which case additional terms and conditions
apply).

Yes, this kind of stuff is a pain.  But it's probably less pain in the
end to
be proactive about it.  Our main duty is making sure that users know
what terms
they are dealing with so that the buck stops at the user rather than at
us.
