+	We could use the EXFUN macro to handle prototype declarations, but

+	simple macro to handle the parameter lists, as in:
+
+	      static int foo PARAMS ((int, char));
+
+	This produces:  `static int foo();' or `static int foo (int, char);'
+
+	EXFUN would have done it like this:
+
+	      static int EXFUN (foo, (int, char));
+
+	but the function is not external...and it's hard to visually parse
+	the function name out of the mess.   EXFUN should be considered
+	obsolete; new code should be written to use PARAMS.
 
     For example:
-	extern int EXFUN(printf, (CONST char *format DOTS));
+	extern int printf PARAMS ((CONST char *format DOTS));
 	int DEFUN(fprintf, (stream, format),
 		  FILE *stream AND CONST char *format DOTS) { ... }
