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'.
