gcc 4.0.1 Memory error during make on AIX 5.0.0.8 using gcc 3.3.3

Hi,
  Any one have any idea why I am getting the following error exit?

/usr/local/bin/gcc   -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_GCC   -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes     -DHAVE_CONFIG_H -DGENERATOR_FILE  -o

make: *** [bootstrap] Error 2

  I have tried running "make" over 6 times and keep getting this message.
  I have no idea what is going on.
  As far as I can tell I have unlimited stack space and such.
I am running this build as root.  I am using the following "configure"
and "make" calls.  I have altered the configure calling parameters with no
change in the end result.  My last attempt was to add the line beginning
--with-cpu... in the configure and by removing -lean from the bootstrap
parameter in the make.

/tmp/GCC/Source/gcc-4.0.1/configure --disable-nls --with-libiconv-prefix=/usr \
      --enable-language=c,c++,f95,objc --disable-shared --disable-multilib --enable-threads=aix \
      --with-cpu=power4 --with-system-zlib

make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap-lean

Bye,
Dwight
