Re: Xen-unstable-staging compilation error

[Michal Novotny <minovotn@redhat.com>]

Well, I've been able to solve this one by adding "typedef int 
Py_ssize_t;" since I was using Python 2.4.3 that doesn't support 
Py_ssize_t natively. However, reinstalling the python was not the option 
because of the system dependencies so I downloaded source code for 
Python-2.7 and investigated this further. There was a definition of 
Py_ssize_t as int so I did just add this definition in 
/usr/include/python-2.4/Python.h file and the compilation was successful.

Hope this helps to someone as well,
Michal
