Tue Sep 3 06:29:20 1991 John Gilmore (gnu at cygint.cygnus.com)
Merge with latest FSF versions of these files.
* stab.gnu.h: Add LAST_UNUSED_STAB_CODE.
* stab.def: Update to GPL2. Move N_WARNING out, since not a
debug symbol. Change comments, and reorder table to numeric
order. Update final table comment.
(N_DSLINE, N_BSLINE): Renumber from 0x66 and 0x68, to 0x46 and 0x48.
Fri Aug 23 01:54:23 1991 John Gilmore (gnu at cygint.cygnus.com)
* a.out.gnu.h, a.out.sun4.h: Make SEGMENT_SIZE able to depend
on the particular a.out being examined.
* a.out.sun4.h: Define segment sizes for Sun-3's and Sun-4's.
* FIXME: a.out.gnu.h is almost obsolete.
* FIXME: a.out.sun4.h should be renamed a.out.sun.h now.
Wed Aug 21 20:32:13 1991 John Gilmore (gnu at cygint.cygnus.com)
* Start a ChangeLog for the includes directory.
* a.out.gnu.h (N_FN): Fix value -- was 15, should be 0x1E.
* stab.def: Update allocation table in comments at end,
to reflect reality as I know it.
