build/ directory

A mix of old "OVM" scripts and new oil-native Ninja scripts.

Old CPython Slice

Quick smoke test:

build/old-ovm-test.sh test-oil-bundle

Python Behavior Changes

Almost all changes remove unused code, but here is a list of behavior changes:

• Objects/typeobject.c : type_new() -- I commented out _Py_Mangle. This turns self.__foo into something else. That won't break my code, but it might break third-party code?
  • TODO: Perhaps find the corresponding compile-time time check in compiler2?
