1.1 root 1: /* tdef.hd -- Definitions for the C pre-processor.
2: *
3: *
4: *
5: *
6: * The first defines here (copied from the first page of n1.c)
7: * control the generation of various permutations of the nroff/
8: * troff programs. This single set of source files generates
9: * both nroff and troff, on the PDP-11, VAX, UNIVAC UNIX, TSO
10: * (as in IBM), and soon () the 3B-20 Processors without
11: * any special compilation procedures, except for the need to define
12: * the symbol 'NROFF' when compiling nroff. By default, compilation
13: * will produce troff.
14: *
15: * Some other compilation options are available for building
16: * a customized version of nroff or troff. A list of definable
17: * symbols and their effect is given here:
18: *
19: *
20: * SMALL Produce a version of nroff or troff that uses a
21: * minimum amount of instruction space. This symbol
22: * automatically defines NDIAGS and NOCOMPACT (see below).
23: * It also causes the following features to be missing:
24: * requests ! and pi, troff paper accounting.
25: *
26: * INCORE Causes nroff/troff to keep both the suffix table (for
27: * hyphenation) and the /tmp file in main memory.
28: * This version of nroff/troff has a minimum of inter-
29: * action with the operating system, but a maximum of
30: * main memory size. Not recommended on minis, and probably
31: * won't work at all on the 11. It also uses standard
32: * I/O, and hence is portable to non-UNIX C environments.
33: * Automatically sets NOCOMPACT.
34: *
35: * NDIAGS Causes the pm request to not be included.
36: *
37: * NOCOMPACT Produces an nroff/troff without compacted macros. The
38: * -c command line option is synonymous with -m, and
39: * the -k option is missing.
40: *
41: * tso Use TSO-style standard I/O
42: *
43: *
44: * All these symbols will cause a suitably modified 'what' command
45: * response when applied to the object nroff or troff.
46: *
47: * Finally, the symbols expected to be set by the C compiler are:
48: *
49: * unix If this is the UNIX operating system. If this symbol
50: * is not defined, it causes the automatic definition of
51: * INCORE, SMALL, and tso. The latter is used to control
52: * generation of standard I/O calls.
53: *
54: * ebcdic Produces code to run on a machine with ebcdic as its native
55: * character set. nroff/troff still runs in ASCII internally
56: * and expects ASCII input, but does produce ebcdic on the
57: * standard output channel.
58: *
