  NOTE TO CONTRIBUTORS: This file, and all the other C-Kermit files, must be
  compatible with C preprocessors that support only #ifdef, #else, #endif,
  #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 inlcude all
  material required by all other C-Kermit modules, including the non-Kermit
  specific ones.

 Debug and transaction logging is included automatically unless you define
 NODEBUG or NOTLOG.  Do this if you want to save the space and overhead.
 (Note, in version 4F these definitions changed from "{}" to the null string
 to avoid problems with semicolons after braces, as in: "if (x) tlog(this);
 else tlog(that);"

  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 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.

  Whether to use ckmatch() in all its glory for C-Shell-like patterns.
  If CKREGEX is NOT defined, all but * and ? matching are removed from
  ckmatch().  NOTE: Defining CKREGEX does not necessarily mean that ckmatch()
  regexes are used for filename matching.  That depends on whether zxpand()
  in ck?fio.c calls ckmatch().  NOTE 2: REGEX is a misnomer -- these are not
  regular expressions in the computer-science sense (in which, e.g. "a*b"
  matches 0 or more 'a' characters followed by 'b') but patterns (in which
  "a*b" matches 'a' followed by 0 or more non-b characters, followed by b).
