+/*============================================================================
+**	On Intel Pentium processors (especially PIII and probably P4), converting
+**	from float to int is very slow. To meet the C specs, the code produced by
+**	most C compilers targeting Pentium needs to change the FPU rounding mode
+**	before the float to int conversion is performed.
+**
+**	Changing the FPU rounding mode causes the FPU pipeline to be flushed. It
+**	is this flushing of the pipeline which is so slow.
+**
+**	Fortunately the ISO C99 specifications define the functions lrint, lrintf,
+**	llrint and llrintf which fix this problem as a side effect.
+**
+**	On Unix-like systems, the configure process should have detected the
+**	presence of these functions. If they weren't found we have to replace them
+**	here with a standard C cast.
+*/
+
+/*
+**	The C99 prototypes for lrint and lrintf are as follows:
+**
+**		long int lrintf (float x) ;
+**		long int lrint  (double x) ;
