People should also note that a big reason for doing this is to improve
floating point support on FreeBSD.  The old floating point emulator
was getting in the way of those improvements.  I'd expect to see a
number of changes to libm over the coming days and weeks.  I'd also
hope to see long double support improved in i386 like it is in amd64
right now...
