Further testing...

I added an extremely simple hack in util.py so that a archive (AIX library) name got returned.

Also in this case - the     print cdll.LoadLibrary("libc.a") fails.

   +74  if os.name == "posix" and sys.platform == "darwin":
   +75      from ctypes.macholib.dyld import dyld_find as _dyld_find
   +76      def find_library(name):
   +77          possible = ['lib%s.dylib' % name,
   +78                      '%s.dylib' % name,
   +79                      '%s.framework/%s' % (name, name)]
   +80          for name in possible:
   +81              try:
   +82                  return _dyld_find(name)
   +83              except ValueError:
   +84                  continue
   +85          return None
   +86
   +87  if os.name == "posix" and sys.platform.startswith("aix"):
   +88       def find_library(name):
   +89          expr = "lib" + name + ".a"
   +90          return expr
   +91
   +92  elif os.name == "posix":
   +93      # Andreas Degert's find functions, using gcc, /sbin/ldconfig, objdump
   +94      import re, tempfile, errno
   +95
   +96      def _findLib_gcc(name):

  +275          else:
  +276              print cdll.LoadLibrary("libc.a")
  +277              print cdll.LoadLibrary("libm.so")
  +278              print cdll.LoadLibrary("libcrypt.so")

OSError:        0509-022 Cannot load module /usr/lib/libc.a.
        0509-103   The module has an invalid magic number.

So, what needs to be returned so that cdll.LoadLibrary could use that result? (e.g., I know that the default libm.a has no shared members on AIX 5.3 TL7 - but libc.a does (shr.o and more, but not all!).
