application. Some of the linker flags ought to get moved to this field someday. archures.c (bfd_default_scan): Recognize a few more numbers: 80486, 80960, and 960. bfd-in.h, bfd.c, targets.c, coffcode.h, coff-mips.c, other targets: Moved COFF swap table to backend data. hosts/i386linux.h: Include unistd.h. aoutx.h, libaout.h, stab-syms.c: stab names are now in constant storage. trad-core.c: Fixed some `PARAMS' uses that were missing parentheses. aoutx.h, archive.c, archures.c, coffcode.h, ctor.c, reloc.c, syms.c: Doc fixes.
