24 * Define symbols to identify the version of Unix this is.
25 * Define all the symbols that apply correctly.

40 It sets the Lisp variable system-type. */

44 /* NOMULTIPLEJOBS should be defined if your system's shell
45 does not have "job control" (the ability to stop a program,

50 /* Emacs can read input using SIGIO and buffering characters itself,
51 or using CBREAK mode and making C-g cause SIGINT.
52 The choice is controlled by the variable interrupt_input.
53 Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
55 SIGIO can be used only on systems that implement it (4.2 and 4.3).
56 CBREAK mode has two disadvantages
57 1) At least in 4.2, it is impossible to handle the Meta key properly.
58 I hear that in system V this problem does not exist.
59 2) Control-G causes output to be discarded.
60 I do not know whether this can be fixed in system V.
62 Another method of doing input is planned but not implemented.
63 It would have Emacs fork off a separate process
64 to read the input and send it to the true Emacs process
69 #define INTERRUPT_INPUT
72 * Define HAVE_SOCKETS if the system supports sockets.
78 * Define HAVE_UNIX_DOMAIN if the system supports Unix
82 #define HAVE_UNIX_DOMAIN
85 * Define HAVE_PTYS if the system supports pty devices.
91 * Define NONSYSTEM_DIR_LIBRARY to make Emacs emulate
92 * The 4.2 opendir, etc., library functions.
