  22         Macros
  23                 PTR             - Generic pointer type
  24                 LONG_DOUBLE     - `long double' type
  25                 CONST           - `const' keyword
  26                 VOLATILE        - `volatile' keyword
  27                 SIGNED          - `signed' keyword
  28                 PTRCONST        - Generic const pointer (void *const)
  29
  30         EXFUN(name, prototype)          - declare external function NAME
  31                                           with prototype PROTOTYPE
  32         DEFUN(name, arglist, args)      - define function NAME with
  33                                           args ARGLIST of types in ARGS
  34         DEFUN_VOID(name)                - define function NAME with no args
  35         AND                             - argument separator for ARGS
  36         NOARGS                          - null arglist
  37         DOTS                            - `...' in args
  38
  39     For example:
  40         extern int EXFUN(printf, (CONST char *format DOTS));
  41         int DEFUN(fprintf, (stream, format),
  42                   FILE *stream AND CONST char *format DOTS) { ... }
  43         void DEFUN_VOID(abort) { ... }
