hi all,
i am having some problem with bn_mul_add_words, my gprof profiling shows it
is very cpu intensive. can we optimize it for the windows version.

below is my gprof call graph.

index % time    self  children    called     name
                                                 <spontaneous>
[1]     50.1   17.99    0.00                 bn_mul_add_words [1]
