Hi

latest grass7 build fails in swig/python with:

Py_ssize_t is defined in /usr/include/python2.4/pymem.h, so I guess that
needs to be #included somewhere?

I can't reproduce this.

Py_ssize_t is defined in /usr/include/python2.4/pymem.h, so I guess that

It shouldn't be necessary to include headers other than <Python.h>.
SWIG should add that include itself.

Probably related to the Swig version. Which version of swig do you
use. With swig 1.3.29 the wrap C files do not include typedef for
Py_ssize_t which are needed for Python <= 2.4.
