/* ANSI and traditional C compatibility macros

   ANSI C is assumed if __STDC__ is #defined.

   VA_START(ap, var)    va_start(ap, var)       va_start(ap)

   Note that it is safe to write "void foo();" indicating a function
   with no return value, in all K+R compilers we have been able to test.

   For declaring functions with prototypes, we also provide these:

   PARAMS ((prototype))
   -- for functions which take a fixed number of arguments.  Use this
   when declaring the function.  When defining the function, write a
   K+R style argument list.  For example:

        char *strcpy PARAMS ((char *dest, char *source));
        ...
        char *
        strcpy (dest, source)
             char *dest;
             char *source;
        { ... }


   VPARAMS ((prototype, ...))
   -- for functions which take a variable number of arguments.  Use
   PARAMS to declare the function, VPARAMS to define it.  For example:

        int printf PARAMS ((const char *format, ...));
        ...
        int
        printf VPARAMS ((const char *format, ...))
        {
           ...
        }

   For writing functions which take variable numbers of arguments, we
   also provide the VA_OPEN, VA_CLOSE, and VA_FIXEDARG macros.  These
   hide the differences between K+R <varargs.h> and C89 <stdarg.h> more
   thoroughly than the simple VA_START() macro mentioned above.

   VA_OPEN and VA_CLOSE are used *instead of* va_start and va_end.
   Immediately after VA_OPEN, put a sequence of VA_FIXEDARG calls
   corresponding to the list of fixed arguments.  Then use va_arg
   normally to get the variable arguments, or pass your va_list object
   around.  You do not declare the va_list yourself; VA_OPEN does it
   for you.

   Here is a complete example:

        int
        printf VPARAMS ((const char *format, ...))
        {
           int result;

           VA_OPEN (ap, format);
           VA_FIXEDARG (ap, const char *, format);

           result = vfprintf (stdout, format, ap);
           VA_CLOSE (ap);

           return result;
        }


   You can declare variables either before or after the VA_OPEN,
   VA_FIXEDARG sequence.  Also, VA_OPEN and VA_CLOSE are the beginning
   and end of a block.  They must appear at the same nesting level,
   and any variables declared after VA_OPEN go out of scope at
   VA_CLOSE.  Unfortunately, with a K+R compiler, that includes the
   argument list.  You can have multiple instances of VA_OPEN/VA_CLOSE
   pairs in a single function in case you need to traverse the
   argument list more than once.

   For ease of writing code which uses GCC extensions but needs to be
   portable to other compilers, we provide the GCC_VERSION macro that
   simplifies testing __GNUC__ and __GNUC_MINOR__ together, and various
   wrappers around __attribute__.  Also, __extension__ will be #defined
   to nothing if it doesn't work.  See below.

   This header also defines a lot of obsolete macros:
   CONST, VOLATILE, SIGNED, PROTO, EXFUN, DEFUN, DEFUN_VOID,
   AND, DOTS, NOARGS.  Don't use them.  */
