K&R requires return value declarations when the return value isn't a
(promoted) int. Section 4.2 ("Functions Returning Non-Integers") of
"The C Programming Language" (1st ed.) goes into more detail; specifically,
at the bottom of page 69,
Second, and just as important, the *calling* routine must state
that atof returns a non-int value. (emphasis theirs)
