Oh, shoot! I was looking at this website: http://gcc.gnu.org/libstdc++/, which mentions that version 3.1 has been released, but I didn't notice that the year was 2002! Now I realised that mine is a pretty ancient one after reading your mails and looking at http://gcc.gnu.org There was a newer version installed in /usr/local btw, which I didn't notice. I have put that in LD_LIBRARY_PATH and there are no more linker problems now. Thanks!
