The 4.3BSD math library, which as I recall it is nearly public domain,
would be a better place to start for most modern machines.  Kahan et al,
the authors of it (and major contributors to the IEEE floating-point
standard), observe that Cody&Waite was written in the Bad Old Days and
is not ideal for relatively well-behaved floating-point hardware like
the IEEE-compatible chips (8087, 68881, etc.).
