/*
|

|
** 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.
