+ * buildsym.c (finish_block): If finishing a function without known
+ parameter type info, set that from parameter symbols.
+ * c-typeprint.c (c_type_print_varspec_suffix): For TYPE_CODE_FUNC,
+ print parameter types, if available.
+ * ch-typeprint.c (chill_type_print_base): Likewise.
+
+ * gdbtypes.h (struct type): Remove function type field.
+ (TYPE_FUNCTION_TYPE): Remove macro. We can't as simply re-use
+ function types now that we're also storing parameter types.
+ And the payoff is much less.
+ * gdbtypes.c (make_function_type): Don't use/set TYPE_FUNCTION_TYPE.
+ (recursive_dump_type): Don't print TYPE_FUNCTION_TYPE.
+ * dwarfread.c (read_subroutine_type): Don't set TYPE_FUNCTION_TYPE.
+

* buildsym.c (start_subfile): Set language for f2c like for cfront.
