* 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)
