,Wed Oct 28 16:11:57 1992 Steve Chamberlain (sac@thepub.cygnus.com) 

* ieee.c (get_symbol): can now cope when two symbols of a
	different class, but the same index number occur consecutively.
	(get_section_entry): nicer name for sections being forward
	referenced. (ieee_archive_p): don't free the filename string,
	since it was never malloced.
