Re: [ballen@uwm.edu] libc/2269: triginometric argument reduction error in libm

This is absolutely beside the point.  If you have a computation where
you need trigonometric functions and you have values large enough to
have problems with the range reduction, your computations are already
so completely wrong that it is of no help to slow down the
implementations of the trigonometric functions.  Fix your program.
