Hi Ralf, Eric,

No idea.
My .bashrc contains "export CDPATH=/some/path:/or:/another" but I've
not marked it readonly.

On the other hand, I've just unpacked autoconf-2.63 in /tmp and rerun
the testsuite, and this time it worked without any problems.

I'll report if I stumble over this or another error.

Cheers,
 Thomas
