+ * 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
