commit 849c2fd894aa87a7e40c71e8d5bda5392b1205be

    Look for sqrt(), possibly in libm.
    
    The unit tests now use sqrt(), which in some platforms (notably
    DragonFlyBSD and Solaris) is not in libc but rather libm.  Since only
    the unit tests use this, add TESTLIBS and if necessary put libm in it.
