No, the code given is exactly what I wanted to show. (The code you
provided was Windows code and I tested it under Windows without
complaints.)
Unfortunately, under Linux you cannot switch to "traditional" since it
would clash with libc which is an ISO C library. Under Solaris
(SPARCWorx) you may want to try -traditional and -fd. As far as I
know only SunOS and HP-UX (besides Windows) come with a native K&R C
compiler. All others do prototype checking.
