Well, it does not need any excessive precision, so why depend on
mathematical library just to compute the three significant digits
of a square root? On the other hand, the Newton's method is very
simple, wide-known and requires very few iterations, so it is
a perfect replacement for that particular purpose.

I should have said 'libresolv is not *always* needed'.
Libicmp uses gethostbyname, which may or may not require libnss or
libresolve. For example, the glibc implementation does not
require any additional libraries. On other systems, it will
require libnss.
