+
+   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
