I've made another branch for this, with a different twist.  I'm not
sure it'll be interesting, but I think it'll solve my immediate need
until I can get around to reasonable testing of the performance
implications.

The "fdrake-optional-64bits" branch will compile using the C "int"
type for "I" keys and values by default, and using the "PY_LONG_LONG"
type if ZODB_64BIT_INTS is defined.

This allows 64-bit BTrees by building ZODB like this:

    python setup.py build_ext -D ZODB_64BIT_INTS build

BTrees.IIBTree.using64bits will be True if ZODB_64BIT_INTS is used.
