We *always* generate this file, and we depend on its existence. The idea behind HAVE_CONFIG_H was being able to include random files from different projects, back in a time where "libraries" were literally just random files instead of actual shared objects. Since we're not in the '80s any more, and our build system(s) define HAVE_CONFIG_H *and* generate the config.h header file, we don't need a conditional guard around its inclusion.
