tests/with-compilation-unit.impure.lisp

   1 ;;;; This file is for testing WITH-COMPILATION-UNIT (particularily the
   2 ;;;; suppression of undefined-foo warnings for forward-references).

   4 ;;;; This software is part of the SBCL system. See the README file for
   5 ;;;; more information.

   7 ;;;; While most of SBCL is derived from the CMU CL system, the test
   8 ;;;; files (like this one) were written from scratch after the fork
   9 ;;;; from CMU CL.
