So, cond.c is the only thing in make that includes math.h
and appears not to need it.  The patch below removes the include.
Why?  To minimize dependencies when building on non-netbsd platforms 
eg SunOS needs to then have libm available.

Anyone think of a reason to keep the math.h include?

Thanks
