*
* 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): default
* (b) GNU Assembler gas: define USE_GAS or GNU_ASSEMBLER
* (c) Amsterdam Compiler kit: define ACK_ASSEMBLER
*
* 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
