I just wanted to say that I didn't manage to solve this issue. In
addition to the below, I tried: (A) bootstrapping with an older version
of GCC (3.4.6) and (B) bootstrapping with ICC 12.0.0. I should've also
mentioned that I'm rm -rf 'ing objdir between tries. I offered a small
bounty for this on Super User, with no luck so far.

Hey Jonathan,
Thanks for the ideas. I tried:
1) removing the '-j 16'
2) using an absolute path when calling configure.
3) using the contrib/download_prerequisites script to download
mpfr-2.4.2, gmp-4.3.2, and mpc-0.8.1, instead of the newer versions
above.
4) setting the PWDCMD environment variable to an automounter-aware pwd
command (pawd).
None of these things resolved the issue. I'm out of ideas for now, so
I posted the question on Super User:
http://superuser.com/questions/592552/bootstrap-error-while-compiling-gcc-4-8-0
If the answer comes up here then I'll post it there and vice versa.

Your procedure looks fine, I'm not sure why you get the bootstrap
comparison errors.
Does objdir definitely not exist before you start?
Have you tried without -j16 ? It certainly should work with parallel
builds, but it could be worth checking that there isn't some problem
caused by that in your environment.

Hello all,
I'm getting bootstrap errors while trying to install GCC and could
use some
help. I'm trying to compile my own copy of GCC from source, in my home
directory on a shared system (cluster). The cluster has GCC 4.4.3
that I'm
using to bootstrap the compilation. I wrote this little script to
show what
I'm doing and to help in debugging:
# Installation parameters
gccver=4.8.0
gmpver=5.1.1
mpcver=1.0.1
mpfrver=3.1.2
prefix=$HOME/local
langs=c,c++
# Download source
wget
ftp://gnu.mirror.iweb.com/gnu/gcc/gcc-${gccver}/gcc-${gccver}.tar.gz
wget ftp://ftp.gnu.org/gnu/gmp/gmp-${gmpver}.tar.bz2
wget ftp://ftp.gnu.org/gnu/mpc/mpc-${mpcver}.tar.gz
wget ftp://ftp.gnu.org/gnu/mpfr/mpfr-${mpfrver}.tar.gz
# Unpack source
tar -xzvf gcc-${gccver}.tar.gz
tar -xjvf gmp-${gmpver}.tar.bz2
tar -xzvf mpc-${mpcver}.tar.gz
tar -xzvf mpfr-${mpfrver}.tar.gz
# Move dependency source directories into gcc source directory
mv gmp-${gmpver} gcc-${gccver}/gmp
mv mpc-${mpcver} gcc-${gccver}/mpc
mv mpfr-${mpfrver} gcc-${gccver}/mpfr
# create a build directory and change to it
mkdir objdir
pushd objdir
# configure, make, check, and install gcc:
../gcc-${gccver}/configure --prefix=${prefix}
--enable-languages=${langs}
make -j 16
make install
# return to the original directory
popd
The above fails during 'make' with the error: "Bootstrap comparison
failure!" I've attached the last few pages of output as error.txt. If
anyone has any suggestions then I'd be really happy to hear them.
Also, let
me know what other information I can provide that would be relevant.
