Greetings!
It has been a long time since I've posted to a gcc list of any kind,
so if I've chosen the wrong list or if I commit some kind of faux pas,
please bear with me.
I recently tried to bootstrap gcc-4.2.2 including binutils-2.18 and
ran into problems, so I thought I would share my experiences in case
others find this documentation useful.
Here are the steps I took:
cd /usr/local/src
tar xf gcc-core-4.2.2.tar.bz2
tar xf gcc-g++-4.2.2.tar.bz2
tar xf gcc-testsuite-4.2.2.tar.bz2
tar xf binutils-2.18.tar.bz2
cd ./gcc-4.2.2
for f in bfd binutils gas gprof ld opcodes; do
ln -s ../binutils-2.18/$f .
done
mkdir /usr/local/build/gcc-4.2.2
cd /usr/local/build/gcc-4.2.2
../../src/gcc-4.2.2/configure
make bootstrap
This yielded the following error:

The following commands enabled me to supply the unresolved external:
cd /usr/local/src/gcc-4.2.2/libiberty
ln -s ../../binutils-2.18/libiberty/filename_cmp.c

With this patch installed, I could re-run configure and 'make
bootstrap' ran to completion.
