[Numpy-discussion] numpy, Py_ssize_t, cython and 64 bits python 2.4

[Dag Sverre Seljebotn]

For mailing list archival purposes, I'm posting the conclusion of this 
story: An update to Cython which also works with NumPy/Python2.4/64-bit 
can now be retrieved from http://hg.cython.org/cython

That Mercurial repo contains previous release + bugfixes deemed to be 
very safe, so I recommend using this instead for SciPy etc. until the 
next Cython release.
