OK, so you're asking how to make a module builtin. I haven't done that
myself, but let me give you a hint where to look: there is list of
builtin modules sys.builtin_module_names if you search the whole python
source distribution for some of the names in the list you'll get list
of files where to look. I've just searched and found that only two
files are involved: PC\config.c and setup.py
