 *
 * Select the syntax appropriate to the 386 assembler being used
 * To add support for more assemblers add more columns to the CHOICE
 * macro.  Note that register names must also have uppercase names
 * to avoid macro recursion. e.g., #define ah %ah recurses!
 *
 * NB 1.  Some of the macros for certain assemblers imply that the code is to
 *	  run in protected mode!!  Caveat emptor.
 *
 * NB 2.  486 specific instructions are not included.  This is to discourage
 *	  their accidental use in code that is intended to run on 386 and 486
 *	  systems.
 *
 * Supported assemblers:
 *
 * (a) AT&T SysVr4 as(1):	define ATT_ASSEMBLER
 * (b) GNU Assembler gas:	define GNU_ASSEMBLER (default)
 * (c) Amsterdam Compiler kit:	define ACK_ASSEMBLER
 * (d) The Netwide Assembler:	define NASM_ASSEMBLER
 * (e) Microsoft Assembler:	define MASM_ASSEMBLER (UNTESTED!)
 *
 * The following naming conventions have been used to identify the various
 * data types:
 *		_SR = segment register version
 *	Integer:
 *		_Q = quadword	= 64 bits
 *		_L = long	= 32 bits
 *		_W = short	= 16 bits
 *		_B = byte	=  8 bits
 *	Floating-point:
 *		_X = m80real	= 80 bits
 *		_D = double	= 64 bits
 *		_S = single	= 32 bits
 *
