This doesn't work for me..... 

runtest --tool libstdc++ --srcdir=/mnt/hd/src/gcc/libstdc++-v3/testsuite

Clearly, I am doing something wrong. I followed the instructions exactly.

I'm using mainline gcc sources for the testuite directory, and gcc-4.0.0 for the installed compiler. This is x86/linux. I tried both bash and tcsh.
