[C++-sig] Boost.Python and python 3.x?

[Ralf W. Grosse-Kunstleve]

Hi Andrew,

Yes, the GSoC project was finished.
I checked in a few Python3 related fixes after the
1.45 release that may be important for you, in
particular the one below, which you could easily apply
manually to your installation.

 /* 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
