Of course it does, because that's a function prototype, which was only
recently added to the C language.  AT&T UNIX C compilers up to SVR4
support a flavor of C modeled after K&R 1st Edition Appendix A, with
some common extensions (enums, struct copy, void).  I am told that the
UNIX SVR4 C compiler will conform to the (forthcoming) ANSI C standard,
which includes function prototypes.  Until then, you must leave the
argument declarations out of your function declarations.
