* trad-core.c: Document how to use it nowadays.
* i386aout.c, newsos3.c: Clean up.
* i386coff.c: Allow 386 coff files to be used as core files too
(for reading core files from embedded systems).
+Thu Oct 10 17:54:08 1991 John Gilmore (gnu at cygnus.com)
+
+ * config/*: trad-core support is HOST dependent, not target
+ dependent. Target config files only set DEFAULT_VECTOR and/or
+ other vector elements. Exception: when host-aout.c is in use,
+ in which case we're forced to assume we're native (hp, vax,
+ tahoe). Rename XDEPFILES to HDEPFILES.
+ * Makefile.in: Rename XDEPFILES.
+ * config/h-sun*: Don't force static linking.
+ * trad-core.c: Document how to use it nowadays.
+ * i386aout.c, newsos3.c: Clean up.

+ (for reading core files from embedded systems).

+ * Add i386aout.c for a.out support on the i386.
