That was a typo - to be sure I was still finding the versioned ones (the 
previous ones had had a bug that they no longer found the "standard" 
one. I forgot to remove (rather save file before the diff command) - you 
see everything!

Will apply the patch, build in 32 and 64 bit modes, and respond.

Working on that - have been posting some questions on python-list as I 
want to build an interface with an AIX performance library (libperfstat).
Without this library one must run a command and then do some string 
manipulation, and sometimes call a second command once that has been 
found (e.g., uuid calls to get a MAC address, cloud-init to get 
boottime) - things that - with a library do not need a subprocess at all.

But I shall also write up the AIX dlopen() process to explain how both 
.so and .a( works (as the argument to CDLL).
> Another thing: in the last few patches, you dropped the definition of RTLD_MEMBER from Modules/_ctypes/_ctypes.c. Is that intended, or just a temporary thing?
Temporary thing - as I keep hoping for inclusion in Python2 and I recall 
you not wanting to add that into _ctypes on Python2.
