``configure`` now uses a standardized format to forward state, compiler flags, and linker flags to ``Makefile``, ``setup.py``, and ``Modules/Setup``. ``makesetup`` use the new variables by default if a module line does not contain any compiler or linker flags. ``setup.py`` has a new function ``addext()``. For a module ``egg``, configure adds: * ``MODULE_EGG`` with value yes, missing, disabled, or n/a * ``MODULE_EGG_CFLAGS`` * ``MODULE_EGG_LDFLAGS`` ``Makefile.pre.in`` may also provide ``MODULE_EGG_DEPS`` that lists dependencies such as header files and static libs.

Perhaps print an info message?

Good thinking, I plan to add an error message after we have ported all stdlib modules to new system.

Ah, it would have been convenient to be able write for token in shlex.split(cflags) if cflags: :)

You can for token in shlex.split(cflags) if cflags else (): if you really want to but I find the boring vanilla form less clever which is a Good Thing.
