Hi Richard,

  here's the source code. Rename to round.c. 

  I think I must be doing something wrong here. Someone would have noticed that
results from _mm_cvtps_pi16 weren't changing when _MM_SET_ROUNDING_MODE() was
called. -) I'm puzzled by it working with -g, but not with -O3.

  Any additional information I can provide?

  Thanks!
