I have a small program:


	#include <stdio.h>

	void
	subr (double x)
	{
	long	l;

		l = x * 60;
		printf ("%ld\n", l);
	}

	main ()
	{
	long	l;

		l = (1./3.) * 60;
		printf ("%ld\n", l);
		subr (1./3.);
	}

Under SunOS 4.1.1 (SPARC), Solaris 2.5 (SPARC), RISC/os 4, or HP-UX 9,
this program prints "20" and "20".  Under NetBSD/mac68k 1.2D or
OpenBSD/mac68k 2.1 it prints "20" and "19".  The program is contrived,
of course, but seems to indicate something odd that occurs in passing
a double (1./3.) as an argument that does not happen when the double
is used directly.  gcc was used on all machines.

Is this something specific to the Macintosh versions of xxxBSD, perhaps?
