Applications should use the documented interface, which is

	#include <floatingpoint.h>

We seem to have obtained this interface from Sun.  AltaVista finds many
hits on <floatingpoint.h> in SunOS and Solaris man pages, e.g.,

	http://www.sees.bangor.ac.uk/~bill/man/intro3.html

It goes with <sys/ieeefp.h>, which we don't have (we had it in
FreeBSD.1.x, but I moved it to <machine/ieeefp.h> because it was
i386-specific :-).

This interface should be superseded by the C9x <fenv.h> interface.
