 * Program profiling (monitor) header.
 *
 * The layout of the mon.out file created by a call to monitor is
 * as follows:
 *	header (m_hdr)
 *	function count buffer (array of m_funcs)
 *	profil buffer (array of shorts)
 * The profil data scales the pc as follows:
 *	bin number = (pc - low pc) * (scale/2) / (1<<16)
