	PR c/9072 
	* c.opt (Wtraditional-conversion): New.
	(Wconversion): Update description.
	* c-typeck.c (convert_arguments): Warnings for prototypes causing
	type conversions different from what would happen in the absence
	of prototype are now handled by Wtraditional-conversion.
	* doc/invoke.texi (Wtraditional-conversion): New.
	(Wconversion): Update description.
	* doc/trouble.texi (Wconversion): Replace Wconversion by
	Wtraditional-conversion.
