I just tried them and I see the FreeBSD box is set to 53 bit precision,
but the problem is that these functions do not exist on Linux. This
means I cannot compile the program to test what the precision is
under linux emulation. The problem I have is that the linux binaries
running under freebsd gives a different result that the freebsd binary
or the linux binary under linux.
