23 * Define symbols to identify the version of Unix this is.
24 * Define all the symbols that apply correctly.
38 /* SYSTEM_TYPE should indicate the kind of system you are using.
39 It sets the Lisp variable system-type. */
41 #define SYSTEM_TYPE "berkeley-unix"
43 /* NOMULTIPLEJOBS should be defined if your system's shell
44 does not have "job control" (the ability to stop a program,
45 run some other program, then continue the first one). */
47 /* #define NOMULTIPLEJOBS */
49 /* Emacs can read input using SIGIO and buffering characters itself,
50 or using CBREAK mode and making C-g cause SIGINT.
51 The choice is controlled by the variable interrupt_input.
52 Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
54 SIGIO can be used only on systems that implement it (4.2 and 4.3).
55 CBREAK mode has two disadvatages
56 1) At least in 4.2, it is impossible to handle the Meta key properly.
57 I hear that in system V this problem does not exist.
58 2) Control-G causes output to be discarded.
59 I do not know whether this can be fixed in system V.
61 Another method of doing input is planned but not implemented.
62 It would have Emacs fork off a separate process
63 to read the input and send it to the true Emacs process

70 if system supports pty's. 'a' means it is /dev/ptya0 */

75 * Define HAVE_TIMEVAL if the system supports the BSD style clock values.
76 * Look in <sys/time.h> for a timeval structure.
82 * Define HAVE_SELECT if the system supports the `select' system call.
88 * Define HAVE_SOCKETS if the system supports sockets.
94 * Define HAVE_PTYS if the system supports pty devices.
100 * Define NONSYSTEM_DIR_LIBRARY to make Emacs emulate
101 * The 4.2 opendir, etc., library functions.
104 /* #define NONSYSTEM_DIR_LIBRARY */
106 /* Define this symbol if your system has the functions bcopy, etc. */

141 5.4.1 the undump MUST be done on a local file system, or the kernel will

196 you might define certain system call names that don't
