  #define, and #undef.  Please do not use #if, logical operators, or other
  later-model preprocessor features in any of the portable C-Kermit modules.
  You can, of course, use these constructions in platform-specific modules
  when you know they are supported.

/*
  This file is included by all C-Kermit modules, including the modules
  that aren't specific to Kermit (like the command parser and the ck?tio and
  ck?fio modules).  It should be included BEFORE any other C-Kermit header
  files.  It specifies format codes for debug(), tlog(), and similar
  functions, and includes any necessary definitions to be used by all C-Kermit
  modules, and also includes some feature selection compile-time switches, and
  also system- or compiler-dependent definitions, plus #includes and prototypes
  required by all C-Kermit modules.

  Etymology: The name of this file means "C-Kermit Common-C-Language Debugging
  Header", because originally it contained only the formats (F000-F111) for
  the debug() and tlog() functions.  Since then it has grown to include all
  material required by all or most of the other C-Kermit modules, including
  the non-Kermit specific ones.  In other words, this is the one header file
  that is guaranteed to be included by all C-Kermit source modules.

  The UNIX Seventh Edition (1979) compiler doesn't allow a lot of -D's on
  the make command line and big modules can result in nonsensical fatal
  compilation errors so I have to remove a lot of features to make it
  compile at all without putting more -D's on the make-command line.

  KFLAGS=-DV7MIN can also be used on other platforms, e.g. Linux, to build
  the smallest possible C-Kermit program, about 400kb: command-line only, no
  script programming, no making network connections, no character-set
  support, dialing of only the most common modem types, no use of external
  processes, and no logging or debugging.  On Ubuntu this results in an
  executable of about 402KB, compared to the normal one of 2.8MB.

  Regarding System V/68 (SV68) (from Gerry Belanger, Oct 2002):

    1) The gethostbyname() appears to return the actual host IP
       address in the hostent struct, instead of the expected pointer
       to the address. Hence the bogus address in the bcopy/memcopy.
       This is despite the header agreeing with our expectations.

    2) the expected argument swap between bcopy and memcopy
       did not happen.  What grief this might cause, I know not.

  We must use a long and convoluted series of #ifdefs that have to be kept in

  We assume that everybody supports: 0, 110, 300, 600, 1200, 2400, 4800, and
  9600 bps.  Symbols for other speeds are defined here.  You can also add
  definitions on the CC command lines.  These definitions affect the SET SPEED
  keyword table, and are not necessarily usable in the system-dependent
  speed-setting code in the ck?tio.c modules, which depends on system-specific
  symbols like (in UNIX) B19200.  In other words, just defining it doesn't
  mean it'll work -- you also have to supply the supporting code in ttsspd()
  and ttgspd() in ck?tio.c.

  The symbols have the form BPS_xxxx, where xxxx is the speed in bits per
  second, or (for bps values larger than 9999) thousands of bps followed by K.
  The total symbol length should be 8 characters or less.  Some values are
  enabled automatically below.  You can disable a particular value by defining
  NOB_xxxx on the CC command line.

/* 2021-10-30 SMS (Steven M Schweda)
 * MAXPATHLEN might have come up undefined because all the consumers
 * should be using CKMAXPATH instead of MAXPATHLEN, or PATH_MAX, or
 * whatever.  The idea was to put all the system dependencies into the
 * definition of CKMAXPATH.  Previously, MAXPATHLEN was not used in
 * ckuus4.c or ckuus6.c,
 *
 * Apparently, I failed to make the required change(s) in UNIX
 * modules/sections ckufio.c, ckuus3.c, ckuus5.c.  (But _I_ didn't spell
 * "#define" as "def".)
 *
 * On VMS, PATH_MAX is defined as 256 in <limits.h>, but that is an
 * obsolete value, which is why NAMX_C_MAXRSS is used instead.
