I'm trying to build JCC on Python 2.4.3 (CentOS 5). However during the

Well, I could work around that one with a patch (see attached) but afterwards
compilation still fails:

I'm using GCC 4.1.2:
gcc-4.1.2-52.el5_8.1
gcc-c++-4.1.2-52.el5_8.1
Any idea what I'm doing wrong? Do you need more info?
In your patch, instead of including "functions.h", add this to JArray.h
after the #include "macros.h" line:
#if PY_VERSION_HEX < 0x02050000
typedef int Py_ssize_t;
#endif
I don't have a Python 2.4 install readily available to test this so I hope
this just works.
Andi..
