According to my ANSI spec quick reference, all the is*() functions, including isspace(), take an int and return an int. In fact, it specifically states that in the intro, and says that legal values are EOF or the range of type `unsigned char'. It also states that thus these functions take values as returned by, say, fgetc(), which returns EOF or 0..255 as an `int'.
