/Ox - Use Maximum Optimization for Speed Uses maximum optimization for fast code.
/P - Create Preprocessor Output File Creates preprocessor-output file.
/QIfist - Suppress _ftol Suppresses the call of the _ftol function when a conversion from floating-point type to integer type is required.

Applies to x86 microprocessors only.

/RTC - Run-time Error Checks Enables run-time error checks.
