I know. What's your suggestion? Switch only to warning? Then it would be
easy to miss warnings. Disabling the valgrind code for gcc < 4.6 is
better, but still not really nice. I thought having part of one file
always use -Werror for this one warning is the best compromise, but I
won't insist on it.
