UCS2/UCS4 detection in Makefile doesn't seem to work here.

Makefile uses distutils.sysconfig, but why not just check sys.maxunicode?

What's your full Python version, OS, distribution and the output of $ python -c "from distutils.sysconfig import get_config_var; print get_config_var('Py_UNICODE_SIZE')" ? It looks like Python 2.4.x and a Debian GNU/Linux distribution. I'm using get_config_var() because it's the obvious choice. It's using the information from pyconfig.h. It's also easier to understand and less error prone than "(sys.maxunicode > 2<<15) and 4 or 2". I usually tend to use the public API instead of reinventing the wheel. Christian
