+       * h8300-tdep.c, tm-h8300.h: turn off some experimental features
+
 Thu Feb 11 00:59:07 1993  John Gilmore  (gnu@cygnus.com)
 
+       * stabsread.c (dbx_lookup_type):  Handle negative type numbers.
+       Previously, would bogusly index off the bottom of type_vector.
+       (rs6000_builtin_type):  Accept type number as argument.
+       (read_type, case '-'):  Handle negatives like any other type number.
+
+       * symfile.c (deduce_language_from_filename):  Handle null name.
+
        * mips-tdep.c (isa_NAN):  Fix byte order dependency.
        Reported by Nobuyuki Hikichi <hikichi@sra.co.jp>,
        fixed by sato@sm.sony.co.jp.
