SUMMARY
In the past, _MSDOS was defined by Microsoft C and C++ compilers. However, Visual C++, 32-bit Edition, does not target 16-bit MS-DOS or 16-bit Windows executables, and therefore some macros are no longer defined. Also, some compiler switches such as /G0 and /Gc are not used with Visual C++, 32-bit Edition.
MORE INFORMATION
Macros not defined by Visual C++, 32-bit Edition are:
_FAST
_QC
M_I86, _M_I86
M_I8086, _M_I8086
M_I286, _M_I286
M_I86xM, _M_I86xM
MS_DOS, _MS_DOS
_WINDLL
_WINDOWS
_PCODE
Compiler switches not recognized by Visual C++, 32-bit Edition are:
