Bug report: Loading a FASL into a package which doesn't import SETQ

[Robert Munyer]

> Trac’in as <https://abcl.org/trac/ticket/475>

I have found that I can "protect" a .abcl file from this bug,
by using these commands:

  unzip foo.abcl __loader__._
  sed -i 's/(setq/(CL:SETQ/ig' __loader__._
  zip -f foo.abcl __loader__._

This is not a proper fix, because it would corrupt any other place
where the five-character sequence "(setq" happens to appear.

A proper fix would probably involve binding *PACKAGE* to a package in
which none of the symbols that are in the content that is about to be
written to __loader__._, other than keywords, are present or inherited.
