+ *
+ * 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
+ *
+ * Author: Gregory J. Sharp, Sept 1992
+ * Vrije Universiteit, Amsterdam, The Netherlands
+ *
+ * [support for Intel syntax added by Josh Vanderhoof, 1999]
