Summary: _ctypes built with GCC on AIX 5.3 fails with ld ffi error
Initial Comment:
Build of Python 2.5 on AIX 5.3 with GCC (tried
multiple versions: 3.3.2 from Bull Freeware, 4.1.0 and
4.1.1 from UCLA) fails with the below error message.
Tried various configure lines, which all get to the
same error, the most simple being:
./configure --disable-ipv6 --with-gcc --with-cxx=g++
(With gcc 3.3.2 I also needed --without-threads)

loewis: No, the ctypes error messages cause the build to
fail. Are you saying to use "gmake -k" or something like that?

You don't need to disable it. It will print error messages,
but you can just ignore them if you don't need the ctypes
module.

The only way I could figure out to disable ctypes was via a
patch to setup.py (included as noctypes.diff). With this
patch applied, Python 2.5 compiles without issues on AIX
5.3 / GCC 4.1.1, and seems to work fine (except for ctypes
of course, and probably some things that depend on ctypes
are also broken). (For the exact build paramaters used, see
attached python-2.5.ep)

As a temporary workaround, is there any way to just disable
building of the ctypes module?

Did a search of the bug database, and found some simular
bugs:
http://python.org/sf/1530448
http://python.org/sf/1544339
http://python.org/sf/1529269
Also tried with --with-system-ffi and some other options,
but got same error:
./configure --disable-ipv6 --with-gcc --with-cxx=g++ --
disable-universalsdk --disable-framework --disable-toolbox-
glue --with-system-ffi --without-threads
Tried adding -Wl,-mimpure-text as in r51113, but that just
caused an error (I might be doing it wrong or something,
specifics below)
