- /* NAME:
- * m-dpx2.h - machine description for Bull DPX/2 range
- *
- * SYNOPSIS:
- * #include "s-usg5-3.h"
- * #include "m-dpx2.h"
- *
- * DESCRIPTION:
- * This header is part of GNU Emacs, and therefore
- * falls under the FSF GPL. There should be a copy of it
- * somewhere on your system (see below).
- *
- * This header file, and a _minor_ change to
- * config.h-dist are all that are needed to build GNU
- * Emacs-18.58 on a Bull DPX/2 model 200 or 300.
- * The DPX/2 500 should probably use a mips based config.
- *
- * The only change _needed_ to config.h (copied from
- * config.h-dist) is to define the appropriate ncl_{el,mr}
- * pre-processor constant. Hopefully in a future release
- * the C compiler will define this automagically :-)
- *
- * If you have INET and X11 loaded, define HAVE_X_WINDOWS
- * before you include this file. If you have INET but not
- * X11 loaded define HAVE_SOCKETS in config.h before you
- * include this file.
- *
- * If you make changes to this file, please be sure to send
- * an update to me: <sjg@melb.bull.oz.au>
- *
- * Please read through this file before attempting to build
- * Emacs. You may need to set SRC_COMPAT=_SYSV in your
- * environment or in Makefile.
- *
- *
- * AMENDED:
- * 92/02/06 12:53:06 (sjg)
- *
- * RELEASED:
- * 92/02/06 12:53:07 v1.7
- *
- * BUGS:
- * There is a problem when running Emacs with its own X
- * window in that if the invoking process terminates,
- * Emacs will terminate shortly afterwards. The following
- * exercises the bug:
- * $ ksh
- * $ emacs &
- * $ exit
- * The emacs process will die within a few minutes of the
- * invoking ksh's termination. Solution? Don't do the
- * above :-)
- *
- * SCCSID:
- * @(#)m-dpx2.h 1.7 92/02/06 12:53:06 (sjg)
