From a3309960a50dbadfd854299e7420223eb8718a56 Mon Sep 17 00:00:00 2001
From: Guido van Rossum <guido@python.org>
Date: Wed, 28 Jul 1993 09:05:47 +0000
Subject: * Added support for X11 modules. * Makefile: change location of FORMS
 library. * posixmodule.c: turn #if 0 into #ifdef MSDOS (stuff in unistd.h or
 not) * Almost all .h files: added CPP magic to avoid duplicate inclusions and
   to support inclusion from C++.
