  If x is not a pointer type I'm sure you mean 
	sizeof ((type *)&x)->member

  This is the portable way to do it, but some compilers will complain
mightily about casting the address of a non-struct to a struct. The most
portable way would be to have a dummy variable of the pointer to struct
type (or use one if you anready have it).
