Probably. But if you are using the most recent releases of newlib, you may
want to try configuring it with --enable-newlib-hw-fp. This may be at the
expense of some accuracy however.

newlib's libm is also based on the "fdlibm" package from Sun. So there is
unlikely to be much difference unless BSD folks have made substantial local
improvements of their own.
