Comment (by dominik.berner@…):

 That's right ssize_t is not defined for MSVC by default, however Python
 2.7.x does define it in pyconfig.h which is used by boost python. the
 define is around ln 198 in pyconfig.h (2.7.4)
 {{{
 /// pyconfig.h
 #ifdef MS_WIN64
 typedef __int64 ssize_t;
 #else
 typedef _W64 int ssize_t;
 #endif
 #define HAVE_SSIZE_T 1
 }}}

 If it's not there boost python does typedef int as ssize_t in
 boost/python/ssize_t.h
