Casting a postdecrement operand

[lwh]

My version of pcc on the IBM RT PC allows the following expression:


		struct abc { char d[500]; };
		struct cba { char e[200]; };
		struct cba *cbap;

		((struct abc *)cbap)++;


to increment cbap by 500. It appears that the ANSI standard doesn't say
anything about the legality of this syntax.  

Does anyone have any experience or opinions on this subject?
