I have no trouble doing what you describe (with Python 2.1.3, 2.2.3,
or 2.3).

The core Pythons I'm using were compiled with MSVC 6 SP5 on Windows
2000 SP4, but I can build extension modules and installers just fine
with MinGW (3.0-rc4).  The only preparatory step was to generate
libpythonXX.a, as described in the Section 6.2.2 of the standard
library docs.

Are you sure your compiler setup is correct?  Was the core Python 2.3
you're using actually built with MSVC 6, as the error message claims?
