* 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.
