4.0.2 bootstrap comparison failure on AIX 5.3

[Albert Chin]

I've built gcc-4.0.2 as follows on AIX 5.3 and am receiving a
bootstrap comparison failure:
  $ cd /opt/build
  $ bzip2 -dc gcc-4.0.2.tar.bz2 | tar xf -
  $ mkdir gcc
  $ cd gcc
  $ CC=/usr/vac/bin/cc CONFIG_SHELL=/opt/fsw/bin/bash \
  /opt/fsw/bin/bash /opt/build/gcc-4.0.2/configure \
  --with-included-gettext --enable-shared --enable-threads \
  --enable-languages="c,c++" --disable-multilib
  ...
  $ gmake bootstrap
  ...
  Bootstrap comparison failure!
  ./fold-const.o differs
  gmake[1]: *** [slowcompare] Error 1
  gmake[1]: Leaving directory `/opt/build/gcc/gcc'
  gmake: *** [bootstrap] Error 2

The AIX 5.3 system:
  $ oslevel -r
  5300-02
  $ lslpp -L vac.C
  vac.C                      7.0.0.3    A     F    IBM XL C Compiler

I don't see anything on
http://gcc.gnu.org/install/specific.html#x-ibm-aix specific to AIX
5.3. I have also built on AIX 5.1 with the same result.
