Log Message:
Add a pair of casts to silence lint about conversion possibly losing bits.

-       v.dblu_dbl.dbl_fracl = frac & 0xffffffff;
-       v.dblu_dbl.dbl_frach = frac >> 32;
+       v.dblu_dbl.dbl_fracl = (u_int) (frac & 0xffffffffULL);
+       v.dblu_dbl.dbl_frach = (u_int) (frac >> 32);

This looks like another bogus lint warning.  Because of the shifts 
and masks, the values are guaranteed to fit in 32 bits.  Please 
could we stop adding casts to appease broken warnings.
