2 | STRING in base BASE to a multiple precision integer. Return a MP_INT |

3 | structure representing the integer. Allow white space in the |

4 | string. If BASE == 0 determine the base in the C standard way, |
---|

5 | i.e. 0xhh...h means base 16, 0oo...o means base 8, otherwise |
---|

6 | assume base 10. |
