+ * Makefile.in (MOSTLYCLEANFILES): Add cfn-operators.pd.
+ (generated_files): Likewise.
+ (s-cfn-operators, cfn-operators.pd): New rules.
+ (s-match): Depend on cfn-operators.pd.
+ * gencfn-macros.c: Expand comment to describe -o behavior.
+ (print_define_operator_list): New function.
+ (main): Accept -o. Call print_define_operator_list.
+ * genmatch.c (main): Add the current directory to the include path.
+ * match.pd (DEFINE_MATH_FN): Delete. Include cfn-operators.pd
+ instead.
