[cmucl-imp] Debian bug 821150: problems with the PCL license [resend]

[Peter Van Eynde]

Hello team,

I fear that someone noticed a problem with the license of the PCL files
in cmucl. The license reads (for example from
https://gitlab.common-lisp.net/cmucl/cmucl/blob/master/src/pcl/boot.lisp):

the problem is the part marked by *, this is a requirement not
compatible with the DFSG. In addition the email and I guess address is
dead.

I've noticed that sbcl never had this clause, and I assume that we can
remove it without someone complaining?

Best regards, Peter
