There are also warnings when cythoning:

    cefpython.cpp(36438) : warning C4244: 'argument' : conversion from 'Py_ssize_t' to 'int',
        possible loss of data
    cefpython.cpp(36462) : warning C4244: 'argument' : conversion from 'Py_ssize_t' to 'int', 
        possible loss of data

Fixes to both v8utils.cpp and process_message_utils.pyx will be to cast to an 
int the result from GetSize().

Upstream CEF does not support VS2008 anymore, so this won't be fixed. 
Apparently it compiles fine for 64bit with the latest VS2013.
