Issue 1435651: Detect incomplete readline implementation (original) (raw)
I'm rejecting this patch as out-of-date. r42562 added a similar change, although restricted to OSX.
If anybody wants to work on it again, I recommend to add checks for exported functions to configure, then query them in setup.py (doing it in distutils is probably impractical, as you would want to cache the result, just as configure output is cached in config.status).
