/* Under 64-bit Windows std::size_t is "unsigned long long". To avoid
getting a Python long for each std::size_t the value is checked before
the conversion. A std::size_t is converted to a simple Python int
if possible; a Python long appears only if the value is too small or
too large to fit into a simple int. */
