	* config/tc-i386.c (i386_operand_modifier): Only match
	modifiers SHORT and FLAT if they are followed by a space.
	(parse_register): When `allow_naked_reg' is set, do not confuse
	identifiers that start with a register name with a register.

	* intel.s, intel.d: Add new tests for naked registers using intel
	syntax.
