After googling a bit, it seems that __int64 is a MSVC type. So, it's
unclear to me if I am getting this error because the default python on
windows is compiled with msvc, or because boost.python only supports
msvc and not mingw.

I tried looking at different documentation, mingw seems to be
explicitely supported by boost in general.

Could someone give me a hint on how to compile boost.python with mingw
or tell me if it's impossible ?

cheers,

Philippe
