Those instructions predate Lion which now defaults gcc/cc to
llvm-gcc-4.2/llvm-g++-4.2 instead of gcc-4.2/g++-4.2. Again
http://llvm.org/bugs/show_bug.cgi?id=9571 is unfixed in Xcode 4.1 which is the
origin of the bootstrap failures. Use CC=gcc-4.2 CXX=g++-4.2 or CC=clang
CXX=clang++ when bootstrapping FSF gcc under Lion.
