Fix for Bug #1334662. Passes make test (other than skipped tests), as well as the errors listed in Bug #1334662. Although it does remove the division from the loop this does not seem to make a signifigant speedup. No clue why. |

This one moves smallmax into a precomputed global table.
$ python2.4 -m timeit 'int("999999999")'
1000000 loops, best of 3: 0.863 usec per loop
$ python2.4 -m timeit 'int("9")'
1000000 loops, best of 3: 0.716 usec per loop
$ ./python -m timeit 'int("999999999")'
1000000 loops, best of 3: 0.766 usec per loop
$ ./python -m timeit 'int("9")'
1000000 loops, best of 3: 0.694 usec per loop
So 0.863 -> 0.766 and 0.716 -> 0.694. 11% and 3%. I
wouldn't bother if it weren't fixing a bug, but maybe the
http://spoj.sphere.pl test will show a larger difference.
