That's actually not my question. Do you have a DLL that contains
all of Python/*.o and Objects/*.o?

I'm giving up for now. I don't quite understand why the file gets
first called libpython2.5.dll.a, and then renamed to libpython2.5.dll.
Could it be perhaps that the .a file is an import library, and actually
different from the .dll file?

That doesn't really matter, I guess. An extension module build by your
port will either fail to load into the regular Python (if
libpython2.5.dll is not found), or load and then crash (because it uses
a different copy of the Python runtime). Likewise vice versa.
If this port ever takes off, we get another binary-incompatible Python
version. I hope that users will understand that it is disjoint from
the python.org version (as they seem to understand fine for the
Cygwin build, which already picks up its extension modules also from
a disjoint location, which helps to keep the two separate).
