/* asmconf.h -- include file for microsoft 80x86 assembler
**** microsoft (r) macro assembler** copyright (c) microsoft corp 1986. all rights reserved**** randy nevin**** Ported to NT by Jeff Spencer 12/90 (c-jeffs).*/
/*
** M8086OPT - When defined causes the 8086 optimized assembly** language functions in asmhelp.asm to be used rather** than the C version. This should not be defined when** building for NT.**** BCBOPT - MASM 5.10A used a cache to hold the source read** from disk. Because of the complexity of this code** and it's negligable speed improvement this** functionality was not duplicated in the NT port of** this code. The constant BCBOPT was used with the** #ifdef preprocessor directive to remove code** associated with the caching system. All code** contained within BCBOPT segments is dead code.**** OS2_2 - Should be defined when producing a version of** masm to run on OS2 2.0.**** OS2_NT - Should be defined when producing a version of** masm to run on NT (any processor). (OS2_2 and** OS2_NT should not be defined at the same time)**** NOFLOAT - When defined disables the assembly of floating** point constants. This is usefull when the library** fuctions strtod and _strtold aren't available in** the C library and this functionality of MASM isn't** needed.**** FIXCOMPILERBUG - When defined allows some ifdef's to go around** some known compiler bugs. This include both CL386 and** MIPS compiler bugs. (These have been reported but not** fixed as of 12/5/90.)**** XENIX - Once upon a time long, long ago was used to build for** XENIX. I garentee this code is broken.** XENIX286 - Dito.**** MSDOS - Generates a hodge-podge of usefull code.** This is automatically defined for OS2_NT and OS2_2.*/
