/*
**	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.
