Sébastien, what does your patch change exactly? Does it build a shared
lib for Python by default? If that's the case, I'm not sure it's a good
idea due to AIX's particular way of treating shared libraries; it might
break e.g. when trying to embed Python in another program.
(I say this while being an AIX novice, but I did have to compile Python
under AIX for embedded use in another third-party software...
unfortunately right now I don't have access to an AIX machine with a
compiler)
