Readline use in trouble?

Here is something I read as part of the Alladin Ghostscript 6.0 beta
release.  I must admit I don't understand the logic of the issue.  It
seems the issue is that you can link non-GPL to GPL libraries, but you
can't distribute the result.   Maybe it doesn't apply to us because we
don't copyright our code.

It seems to suggest that we could be prevented from distributing
readline in the future.  Not sure though.

It sounds like the old US crypto restriction where you couldn't
distribute software that had hooks in it to add crypto.

Removal of readline would certainly affect psql users.

The actual file is gs5.94/doc/Make.htm.1
