 * Program profiling (monitor) header.
 * COH286.
 *
 * A call to monitor() creates a mon.out file structured as follows:
 *	header			struct m_hdr
 *	function count array	struct m_func[m_nfuncs]
 *	profil buffer		short[m_nbins]
 * The profil data scales the pc as follows:
 *	bin number = (pc - low pc) * (scale/2) / (1<<16)
