{UD} Nope, the implementation is correct. The problem is with egcs version
prior to 1.1. I.e., egcs 1.0 to 1.0.3 are all broken (at least on Intel).
If you have to use this compiler you must define __NO_MATH_INLINES before
including <math.h> to prevent the inline functions from being used. egcs 1.1
fixes the problem. I don't know about gcc 2.8 and 2.8.1.
