/clr:noAssembly	/LN (Create MSIL Module)	/clr (Common Language Runtime Compilation)
/Fr	/FR	/FR, /Fr (Create .sbr File)
/Ge	None	/Ge (Enable Stack Probes)
/GX	/EH (Exception Handling Model)	/GX (Enable Exception Handling)

/H	None	/H (Restrict Length of External Names)
/Og	/O1, /O2 (Minimize Size, Maximize Speed)	/Og (Global Optimizations)
/QIfist	No compiler option is needed. The compiler has made significant improvements in float to int conversion speed. Regarding rounding, /QIfist results in generation of the fistp instruction, which uses whatever ambient rounding mode is to do the conversion. A routine to do this is: int ftol_ambient(double d) { int i; __asm { fld d fistp i } return i; }	/QIfist (Suppress _ftol)
/V	None	/V (Version Number)
/Yd	/Z7, /Zi, /ZI (Debug Information Format)	/Yd (Place Debug Information in Object File)
/Ze	None	/Za, /Ze (Disable Language Extensions)
/Zg	None	/Zg (Generate Function Prototypes)
