I think I've found a bug in BN_sub_word.  It appears
that it is not correctly setting the sign of the
resulting BIGNUM.  The following program attempts to
create a BIGNUM with a value of -70, but it instead
ends up with value 70.

$ ./BNTest
Zero: 0
-70:  70

#include <openssl/bn.h>
#include <iostream>

int main (int argc, char**argv)
{
    BIGNUM* neg = BN_new();

    BN_init (neg);
    BN_zero (neg);

    char* pz = BN_bn2dec (neg);

    std::cout << "Zero: " << pz << std::endl;

    BN_sub_word (neg, 70);

    pz = BN_bn2dec (neg);

    std::cout << "-70:  " << pz << std::endl;

    return 0;
}

yep a bug, should be fixed in the next snapshot.

Thanks,
Nils
