/* ANSI and traditional C compatibility macros

   Some ANSI environments are "broken" in the sense that __STDC__ cannot be

   relied upon to have it's intended meaning.  Therefore we must use our own

   concoction: _HAVE_STDC.  Always use _HAVE_STDC instead of __STDC__ in newlib

   sources!

   ANSI C is assumed if _HAVE_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) { ... }
