	* tree-complex.c (expand_complex_libcall): New.
	(expand_complex_multiplication): Use it for c99 compliance.
	(expand_complex_division): Likewise.
	* fold-const.c (fold_complex_add, fold_complex_mult): New.
	(fold): Call them.
	* builtins.c (built_in_names): Remove const.
	* tree.c (build_common_builtin_nodes): Build complex arithmetic
	builtins.
	* tree.h (BUILT_IN_COMPLEX_MUL_MIN, BUILT_IN_COMPLEX_MUL_MAX): New.
	(BUILT_IN_COMPLEX_DIV_MIN, BUILT_IN_COMPLEX_DIV_MAX): New.
	(built_in_names): Remove const.
	* c-common.c (c_common_type_for_mode): Handle complex modes.

It appears that Ada front-end's type_for_mode is not prepared to handle complex
floating-point modes.
