+ Don't allow function parameter names to be the same as function
+ names - required by POSIX. Bug first reported in comp.lang.awk.
+
+ In addition, don't allow use of a parameter as a function name
+ in a call (but it's ok in indirect calls).
+
+ * NEWS: Updated.
+ * awk.h (check_param_names): Add declaration.
+ * awkgram.y (at_seen): New variable. Communicates between
+ yylex() and the parser.
+ (FUNC_CALL production): Check at_seen and check that the identifier
+ is a function name.
+ (parse_program): Call check_param_names() and set errcount.
+ (yylex): Set at_seen after seeing an at-sign.
+ * symbol.c (check_param_names): New function.
+
