  Target Milestone: ---

I tried building gcc-4.9.3 on AIX 7.1 as follows:
  $ gtar jxf gcc-4.9.3.tar.bz2
  $ cd gcc-4.9.3
  $ mkdir .obj
  $ cd .obj
  $ PATH=/opt/TWWfsw/gcc44/bin:$PATH LDR_CNTRL=MAXDATA=0x70000000 \
  ../configure LDFLAGS="-Wl,-brtl -Wl,blibpath:/opt/TWWfsw/libcloog018/lib:\
/opt/TWWfsw/libgmp51/lib:/opt/TWWfsw/libisl012/lib:/opt/TWWfsw/libmpc10/lib:\
/opt/TWWfsw/libmpfr31/lib:/usr/lib" --enable-nls --with-included-gettext \
--enable-shared --enable-threads --enable-languages="c,c++" \
--with-local-prefix=/tmp/gcc49 --with-cloog=/opt/TWWfsw/libcloog018 \
--with-gmp=/opt/TWWfsw/libgmp51 --with-isl=/opt/TWWfsw/libisl012 \
--with-mpc=/opt/TWWfsw/libmpc10 --with-mpfr=/opt/TWWfsw/libmpfr31 \
--prefix=/tmp/gcc49
  ...
  $ PATH=/opt/TWWfsw/gcc44/bin:$PATH LDR_CNTRL=MAXDATA=0x70000000 gmake

The build failed with the following:
