* coffcode.h (coff_add_missing_symbols): if symbols don't come

Browse Source 
from a coff file (csym is null), dont deref them

	* ieee.c (parse_expression): get the answer right when adding an
	abs+(sec+off), (ieee_generic_stat_arch_elt): call ieee_object_p
	on elts so that filename is filled in.
