 *	F_LSYMS		local symbols stripped from file
 *	F_MINMAL	this is a minimal object file (".m") output of fextract
 *	F_UPDATE	this is a fully bound update file, output of ogen
 *	F_SWABD		this file has had its bytes swabbed (in names)
 *	F_AR16WR	this file has the byte ordering of an AR16WR (e.g. 11/70) machine
