From 5e71744000f4a0affc51be3a5276be7e01719049 Mon Sep 17 00:00:00 2001
From: Greg Ward <gward@python.net>
Date: Sat, 14 Aug 1999 23:53:53 +0000
Subject: Changed to use 'spawn()', now that it exists. Added 'verbose' and
 'dry_run' parameters to constructor. Changed 'compile()', 'link_*()' to
 default lists arguments to None   rather than empty list. Added
 implementations of the filename-mangling methods mandated by   the CCompiler
 interface.
