+ * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
+ rather complicated seeming problem. Eliminate LOGICAL_ versions,
+ just make N_XXX work by excluding the header from the text segment.
+ * aoutx.h: Fix comments to match.
+
+Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
+
+ * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
+ LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
+ for the "logical" text segment (i.e. never consider the exec
+ header to be part of the text segment). This change is
+ needed for consistency with various other parts of bfd and ld.
+ * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
+ and move calculation of obj_textsec(abfd)->size to libaout.h.
+ * bfd-in.h: Removed bogus ';'.
+
+ * Makefile.in: Add MINIMIZE flag to select lean
+ or bloated target_vector.
+ * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
+ * newsos3.c: Fixes to ../include/aout64.h remove need
+ for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
+
+Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
+
+ * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
+ handle both little and big-endian targets, with little
+ the default unless TARGET_IS_BIG_ENDIAN_P is defined.
+ * host-aout.c: Add FIXME note.
+
+Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
+
+ * targets.c: Make the default target_vector contain
+ just &DEFAULT_VECTOR. This makes executables a lot smaller.
+ Old behavior can be gotten by defining ALL_TARGETS.
+ * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
+ Factored out common code into new file aout-target.h.
+ Saves a lot of duplicate code for a.out variants.
+
+Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
+
+ Get 'make headers' to work when configured with +subdirs.
+ * Makefile.in: Add $(subdir) to docdir path.
+ * doc/Makefile.in (protos): Add $(srcdir) prefix
+ to name of sed scripts.
