Hi Tobias,

thanks, that does the job after installing some valgrind-devel stuff.

I apparently got stuck readings the description of --enable-checking,
which also mentions valgrind, and then missed the relevant option.

As long as I don't touch code outside fortran/libgfortran and watch
new warnings, it is unlikely to break bootstrap for others.

Thanks,
Harald
