It looks like people often have trouble finding the libstdc++-specific configure options. It is suggested, very sensibly in my opinion, that the documentation should be added to http://gcc.gnu.org/install/configure.html, in a specific section - similarly to Fortran/Java(libgcj) and so on - or, maybe, linked from there. This idea makes even more sense now that libstdc++-v3 is a integral part of the GCC project.
