+'valgrind --tool=memcheck --num-callers=20 --leak-check=yes --leak-resolution=high --show-reachable=yes'.
+
+When CHECKER is not empty, it is recommended that the package has been
+configured with
+ --disable-shared so that tests are real executables and not libtool
+ wrapper scripts, and
+ CFLAGS=\"-g\" so that valgrind shows line numbers.
