OK, that's easy to work around in Xapian code we can use the str()
function which converts a number to a std::string, and so change:

    cout << i;

to be:

    cout << str(i);

This should work everywhere, and this isn't at all performance critical
code, so we can just do it unconditionally.  It's also only relevant to
1.2.x - for 1.3.x you now need C++11 support.  That definitely needs at
least GCC 4.4, and probably realistically something newer.

This patch should help:

If you hit more instances, a similar fix should work.

Cheers,
