It seems to me that exposing interpreter build options via the sys module
would be a Good Thing.  You can mess around with
distutils.sysconfig.get_config_var("CPPFLAGS"), but that is a bit fragile
(the format can change over time or across compilers, making it difficult to
write robust code that sniffs out the useful bits).  Then again, maybe
that's by design.  Still, I think it ought to be easy to discover at runtime
if large file support, threading, or other optional capabilities were
compiled into the interpreter.
