>Description:
As you know, you can compute log_2(x) by: log(x) / log(2).
However, log2*() seems to be a required function for C99. FreeBSD doesn't
support this function at the time of the writing, but there is an open
PR at http://www.freebsd.org/cgi/query-pr.cgi?pr=83845.

I don't know if we can use the patch in that PR since it comes from SunSoft.

I think the NetBSD libc misses some C99 functions so we aren't fully
C99-compliant, but this can be a start.
