Build
- On Unix, a shared libpython2.3.so can be created with --enable-shared.
- References to the CACHE_HASH and INTERN_STRINGS preprocessor symbols
were eliminated. They were always defined, and the internal features
they enabled stopped being experimental long ago.

Building a shared libpython
---------------------------
Starting with Python 2.3, the majority of the interpreter can be built
into a shared library, which can then be used by the interpreter
executable, and by applications embedding Python. To enable this feature,
configure with --enable-shared.
Configuring additional built-in modules
