[Bug libstdc++/19995] New: libstdc++ fails to build correctly on AIX 5.2

["quanah at stanford dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

I had no problem building gcc-3.3.1 on this system.  However, when I went to
build gcc-3.4.3, it failes in the ppc64 portion of libstdc++.  The error given
is the same as seen in this very old thread:

<http://gcc.gnu.org/ml/gcc/2001-06/msg01217.html>

Configure is run as:

cd ../gcc-build/rs_aix52 && CONFIG_SHELL=/usr/pubsw/bin/bash CFLAGS=-O CC=gcc sh
../../gcc-3.4.3/configure \
    --datadir='${prefix}/lib' --libexecdir='${prefix}/lib' \
    --sharedstatedir='${prefix}/lib' --prefix=/usr/pubsw \
    --with-as=/usr/bin/as \
    --with-ld=/usr/bin/ld \
    --with-ar=/usr/bin/ar \
    --with-included-gettext \
    --with-libintl-prefix=/usr/pubsw \
    --with-libiconv-prefix=/usr/pubsw \
    --enable-languages=c,c++,f77,java,objc

The failure error is:
