Compiler Option (specifically Qfport)

I ran my test suites (about 300 files) once with Qfport (rounding) on and once without. Results are the same -- is this expected or is there another option I have on that was negating the rounding effect?

I clean and rebuild the entire project each time.

Qfp-port applies only to x87 code. If you use any SSE option, it should not make any difference. Even in x87 code, it applies only to single precision code, since precision mode is normally set to 53 bits, so that all double precision operations are rounded.
