-# gcc makes no difference between "#define HAVE_FOOBAR" and "#define HAVE_FOOBAR 0" by default,
-# but this too error prone. If you forget to include the config.h, you get weird segfaults.
-# If you include it everywhere, everything gets recompiled everytime.
-# So we include only where needed, and compile with -Wundef to notice the missing includes.
-# But cmake sometimes defines to the empty definition (#define HAVE_VALGRIND_H).
-# So we have to make sure that everything got a decent value before generating the files.
