Python 2.5 compile on x86_64

[Denis Leroy <denis poolshark org>]

Since we updated to python 2.5, glom 1.2.2 is failing to build on 
x86_64. I'm a bit short on time and will not have time to look at this 
in depth before a few days, so if anyone has an easy fix for this


py_glom_related.cc:194: error: invalid conversion from 'int 
(*)(PyObject*)' to 'Py_ssize_t (*)(PyObject*)'

Glom::Record_tp_as_mapping_getitem(Glom::PyGlomRecord*, PyObject*)':

argument 4 has type 'size_t'
