Seems that trying to debug this issue now also destroyed the version I
have on my system (or just the libstdc++, I don't know). What I did today
is:

rebuild binutils 2.21.1 using the gcc-4.5.3 I have installed
rebuild binutils 2.21.1 using the gcc-4.5.3 I have installed once again
rebuild gcc 4.5.3
rebuild binutils 2.21.1 again
created new build directory
cd this build directory
/path/to/cmake-next/configure
make

This fails with:
