Whether or not the program exited successfully.  Zero indicates success,
and nonzero indicates failure.

Because a warning message indicates you're doing something that's
probably wrong unless you really know what you're doing.  (The code you
posted, for instance, is Very Bad.)  Using an explicit cast is a way to
indicate to the compiler (and other people reading your code) that "Yes,
I know this is suspicious, but I really mean to do it."
