-
-   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.  */
