From c7a813af8940173d1dbe0426c554aa6cf7af80c0 Mon Sep 17 00:00:00 2001
From: Thien-Thi Nguyen <ttn@gnuvola.org>
Date: Fri, 6 Apr 2001 09:51:25 +0000
Subject: [PATCH] Update copyright.

Use `export' and `export-syntax' instead of
`define-public' and `defmacro-public'.

(make-thread): Rename first arg to `proc'; nfc.
(begin-thread, monitor): Rename second arg to `rest'; nfc.
(with-mutex): Rename second arg to `body'; nfc.
