 *
 * 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
