Mon Nov 25 17:26:22 1991 Steve Chamberlain (sac at cygnus.com) 

* as.c: (perform_an_assembly_pass): moved declaration of i to
	avoid a syntax error. Now always create the three default
	sections when in MANY_SEGMENTS mode.
	* as.h: New improved way of specifying MANY_SEGMENTS
	* configure.in: hds object format is now coff-bfd
	* subsegs.h: add line numbers and section stuff to the
	segment_info structure. (But go back later and fix.. this is
	COFF specific)
