	* gas/i386/intelok.d: Account for 32-bit displacements being shown
	in hex.

2005-05-25  Jan Beulich  <jbeulich@novell.com>

	* i386-dis.c (OP_E): In Intel mode, display 32-bit displacements in
	hex (but retain it being displayed as signed). Remove redundant
	checks. Add handling of displacements for 16-bit addressing in Intel
	mode.
