/* tdef.hd -- Definitions for the C pre-processor.
*
*
*
*
* The first defines here (copied from the first page of n1.c)
* control the generation of various permutations of the nroff/
* troff programs. This single set of source files generates
* both nroff and troff, on the PDP-11, VAX, UNIVAC UNIX, TSO
* (as in IBM), and soon () the 3B-20 Processors without
* any special compilation procedures, except for the need to define
* the symbol 'NROFF' when compiling nroff. By default, compilation
* will produce troff.
*
* Some other compilation options are available for building
* a customized version of nroff or troff. A list of definable
* symbols and their effect is given here:
*
*
* SMALL Produce a version of nroff or troff that uses a
* minimum amount of instruction space. This symbol
* automatically defines NDIAGS and NOCOMPACT (see below).
* It also causes the following features to be missing:
* requests ! and pi, troff paper accounting.
*
* INCORE Causes nroff/troff to keep both the suffix table (for
* hyphenation) and the /tmp file in main memory.
* This version of nroff/troff has a minimum of inter-
* action with the operating system, but a maximum of
* main memory size. Not recommended on minis, and probably
* won't work at all on the 11. It also uses standard
* I/O, and hence is portable to non-UNIX C environments.
* Automatically sets NOCOMPACT.
*
* NDIAGS Causes the pm request to not be included.
*
* NOCOMPACT Produces an nroff/troff without compacted macros. The
* -c command line option is synonymous with -m, and
* the -k option is missing.
*
* tso Use TSO-style standard I/O
*
*
* All these symbols will cause a suitably modified 'what' command
* response when applied to the object nroff or troff.
*
* Finally, the symbols expected to be set by the C compiler are:
*
* unix If this is the UNIX operating system. If this symbol
* is not defined, it causes the automatic definition of
* INCORE, SMALL, and tso. The latter is used to control
* generation of standard I/O calls.
*
* ebcdic Produces code to run on a machine with ebcdic as its native
* character set. nroff/troff still runs in ASCII internally
* and expects ASCII input, but does produce ebcdic on the
* standard output channel.
*
