Maybe only using the '--disable-build-with-cxx' could succeed... Using 
an intermediate GCC 4.x could however
be the only working way. But whether gcc-4.2 is enough I'm not sure :(

Using the g++-4.1.2 (like in CentOS5) has caused some build crashes when 
using the current '--enable-build-with-cxx'
default in the GCC build. So I myself have used g++-4.6 or g++-4.7 as 
the minimum with g++ as the build compiler.
