Considering that python-2.7.13 is posed for a release - I ask again,
considering that python-2.7.12 (and I expect a few earlier ones) can load "AIX"
.a type shared libraries - if you know how to supply the name -
that my patch be included in python-2.7.13.

In, other words, as is, find_library() will always return None for standard
libraries (will only return a value if "root" has extracted and renamed a
shared library member as a file) - while, if you know the magic that
find_library cannot return - you can load such a library.
IMVHO (in my Very humble opinion) - a bug that has been too long unnoticed -
but can be repaired.
There is no additional ability being added - it is already there. Just making
it more accessible and legible for python programmers on AIX.
If the patch-code needs more cleanup, improvement, etc. - fine. But do not lock
out an easy interface to such a basic function.
regards,
Michael
