* mdebugread.c (parse_symbol): Handle sh.value of zero for enums.

	Determine signedness of enum type from enumerators.
	(parse_type):  Handle btIndirect types, handle fBitfield for
	some non-member types.
	(upgrade_type):  Use TYPE_FLAG_TARGET_STUB for arrays with
	unknown length.
	(cross_ref):  Handle stIndirect forward reference to btTypedef.

	* stabsread.c (read_enum_type):  Determine signedness of enum
	type from enumerators.

	* top.c (execute_command):  Remove trailing whitespace from
	command arguments, except for `set' and `complete' commands.
	(validate_comname):  Allow underscores in user defined command
	names.

	* values.c (modify_field):  Change `Value does not fit in %d bits'
	error to a warning. Exclude sign extension bits of negative field
	values from fit check.
