1.1 root 1: /* NAME:
2: * m-dpx2.h - machine description for Bull DPX/2 range
3: *
4: * SYNOPSIS:
5: * #include "s-usg5-3.h"
6: * #include "m-dpx2.h"
7: *
8: * DESCRIPTION:
9: * This header is part of GNU Emacs, and therefore
10: * falls under the FSF GPL. There should be a copy of it
11: * somewhere on your system (see below).
12: *
13: * This header file, and a _minor_ change to
14: * config.h-dist are all that are needed to build GNU
15: * Emacs-18.58 on a Bull DPX/2 model 200 or 300.
16: * The DPX/2 500 should probably use a mips based config.
17: *
18: * The only change _needed_ to config.h (copied from
19: * config.h-dist) is to define the appropriate ncl_{el,mr}
20: * pre-processor constant. Hopefully in a future release
21: * the C compiler will define this automagically :-)
22: *
23: * If you have INET and X11 loaded, define HAVE_X_WINDOWS
24: * before you include this file. If you have INET but not
25: * X11 loaded define HAVE_SOCKETS in config.h before you
26: * include this file.
27: *
28: * If you make changes to this file, please be sure to send
29: * an update to me: <[email protected]>
30: *
31: * Please read through this file before attempting to build
32: * Emacs. You may need to set SRC_COMPAT=_SYSV in your
33: * environment or in Makefile.
34: *
35: *
36: * AMENDED:
37: * 92/02/06 12:53:06 (sjg)
38: *
39: * RELEASED:
40: * 92/02/06 12:53:07 v1.7
41: *
42: * BUGS:
43: * There is a problem when running Emacs with its own X
44: * window in that if the invoking process terminates,
45: * Emacs will terminate shortly afterwards. The following
46: * exercises the bug:
47: * $ ksh
48: * $ emacs &
49: * $ exit
50: * The emacs process will die within a few minutes of the
51: * invoking ksh's termination. Solution? Don't do the
52: * above :-)
53: *
54: * SCCSID:
55: * @(#)m-dpx2.h 1.7 92/02/06 12:53:06 (sjg)
