Error compiling 64bits gcc 3.2 compiler on Solaris 2.8

[Ziying Sherwin]

We are trying to install gcc 3.2 64 bits compiler on our Solaris 2.8
machine. Currently we are using gcc 2.95.2. We attempted to install gcc 3 
64 bit compiler several time, but encountered some problems each time. This
time, we stil have problems compiling true 64 bit compiler. Here is how we
do it:

 1. Using gcc 2.95.2 compile a 32 bits gcc 3.2 compiler:

      /gcc_3.2.dir/configure \
          --prefix=/depot/package/gcc_3.2_32bit \
          --enable-languages=c,c++,f77,objc \
          --enable-threads
      make bootstrap
      make check
      make install

 2. Using the newly compiled 32 bits gcc 3.2 compiler to compile a 64 bits
    compiler:

      /gcc_3.2.dir/configure \
          --prefix=/depot/package/gcc_3.2_64bit \
          --enable-languages=c,c++,f77,objc \
          --enable-threads \
          --with-as=/usr/ccs/bin/as \
          --with-ld=/usr/ccs/bin/ld \
          --disable-nls
          sparcv9-sun-solaris2
      make bootstrap
      make check   
      make install

  3. Using the newly compiled 64 bits gcc 3.2 compiler to compile a real
     64 bits compiler:

       /gcc_3.2.dir/configure \
          --prefix=/depot/package/gcc_3.2 \
          --enable-threads \
          --with-as=/usr/ccs/bin/as \
          --with-ld=/usr/ccs/bin/ld \
          --enable-languages=c,c++,f77,objc \
          --disable-nls \
          sparcv9-sun-solaris2
       make bootstrap [failed here]

     We got error messages at this point:

Any ideas? Thanks.
