[Bug bootstrap/15581] New: build a new version gcc failure

["psho at hko dot gov dot hk" <gcc-bugzilla at gcc dot gnu dot org>]

I wish to build a gcc 3.3.2 compiler on the IBM P630 AIX5.2 ML 2 machine by
make-3.80 and old gcc compiler version
gcc -v
Reading specs from /usr/bin/../lib/gcc-lib/powerpc-ibm-aix5.1.0.0/2.9-aix51-0202
09/specs
gcc version 2.9-aix51-020209 
and the installation shell script "gcc332.sh" with options
#!/bin/sh
# tar and gz files from melas:/usr/local/src/tarballs, user is finstl
# put them into /home/user1/finstl directory and su - root.
PATH=/usr/bin:$PATH:.
cd /base/source
gunzip < tarballs/gcc-3.3.2.tar.gz | tar xvf -
CC=gcc
cd gcc-3.3.2
./configure \
  --prefix=/usr/local/gcc33 \
  --enable-languages=c,c++,f77
# must use gnu make version 3.8 or later
/usr/local/make380/bin/make -j4 bootstrap
/usr/local/make380/bin/make install
# test the /usr/local/gcc33/bin/gcc in compiler programs



However new gcc build in failure and the following internal compiler error was
happened:
