Compile a source file to byte-code and write out the byte-code cache file.
Compile a source file to byte-code and write out the byte-code cache file.
The source code is loaded from the file name *file*. The byte-code is
written to *cfile*, which defaults to the :PEP:`3147` path, ending in

.. versionchanged:: 3.4
Changed code to use :mod:`importlib` for the byte-code cache file writing.
This means file creation/writing semantics now match what :mod:`importlib`
