/* ANSI and traditional C compatibility macros

   ANSI C is assumed if __STDC__ is #defined.

   Macro    ANSI C definition Traditional C definition
   -----    ---- - ---------- ----------- - ----------
   PTR            `void *'          `char *'
   LONG_DOUBLE    `long double'           `double'
   CONST    `const'                 `'
   VOLATILE `volatile'        `'
   SIGNED   `signed'          `'
   PTRCONST `void *const'           `char *'

   DEFUN(name, arglist, args)

      Defines function NAME.

      ARGLIST lists the arguments, separated by commas and enclosed in
      parentheses.  ARGLIST becomes the argument list in traditional C.

      ARGS list the arguments with their types.  It becomes a prototype in
      ANSI C, and the type declarations in traditional C.  Arguments should
      be separated with `AND'.  For functions with a variable number of
      arguments, the last thing listed should be `DOTS'.

   DEFUN_VOID(name)

      Defines a function NAME, which takes no arguments.

   EXFUN(name, prototype)

      Is used in an external function declaration.
      In ANSI C it is `NAMEPROTOTYPE' (so PROTOTYPE should be enclosed in
      parentheses).  In traditional C it is `NAME()'.
      For a function that takes no arguments, PROTOTYPE should be `(NOARGS)'.

    For example:
      extern int EXFUN(printf, (CONST char *format DOTS));
      int DEFUN(fprintf, (stream, format),
              FILE *stream AND CONST char *format DOTS) { ... }
      void DEFUN_VOID(abort) { ... }
