PR bin/57918 

Redo the previous correctly, the test should be whether or not only the
bottom 32 bits are set, rather than whether any of bits 32..63 are set.
This makes no difference if u_long (or unsigned long long) is 64 bits,
it is the same test in that case, but if u_long were 128 bits there is
a notable difference (though for the particular issue observed in the PR,
it is likely to work either way).
