[Python-Dev] Static builds on Windows

I'm trying to build a static Python library on Windows.

Obviously this can be done by compiling the sources defining the
Py_NO_ENABLE_SHARED preprocessor symbol.

The resulting executable crashes when trying to load external extension
modules, because it tries to load another Python instance (from

Much better, of course, would be if the executable wouild refuse to load
extension modules, which can be forced by commenting out the definition
of HAVE_DYNAMIC_LOADING in PC/pyconfig.h.

Now, shouldn't the definition of this symbol be protected by #ifndef
Py_NO_ENABLE_SHARED, or is there already a different mechanism (without
the need to change the source files)?
