2363 **      On Intel Pentium processors (especially PIII and probably P4), converting
2364 **      from float to int is very slow. To meet the C specs, the code produced by
2365 **      most C compilers targeting Pentium needs to change the FPU rounding mode
2366 **      before the float to int conversion is performed.
2367 **
2368 **      Changing the FPU rounding mode causes the FPU pipeline to be flushed. It
2369 **      is this flushing of the pipeline which is so slow.
2370 **
2371 **      Fortunately the ISO C99 specifications define the functions lrint, lrintf,
2372 **      llrint and llrintf which fix this problem as a side effect.
2373 **
2374 **      On Unix-like systems, the configure process should have detected the
2375 **      presence of these functions. If they weren't found we have to replace them
2376 **      here with a standard C cast.
