Odd to say the least and I am not sure why we even need to link libstdc
++ explicitly here. I assume your C++ compiler works since at that
point we have already build NTL. libstdc++.so should be automatically
picked up the compiler. To fix this I would remove that linker
directive from FLINT.
Does Lenny ship with gcc 4.3.1 or did you compile the compiler itself?
