X-Git-Tag: OpenSSL_0_9_5beta1~68

test_mont was exercising 100-bit multiplication modulus X*I-bit, where
X is 5120 on 32-bit and 151552 on 64-bit architectures and I varies
from 0 to 4. As result the test was *unreasonably* slow and virtually
impossible to complete on 64-bit architectures (e.g. IRIX bc couldn't
even swallow such long lines).
