This has always been true with every version of autoconf --- it's one of
the less well designed aspects of autoconf IMHO.  The GNU folk claim
it's a feature, but I don't think so... (*)

(*) their reasoning is that you can pass the same set of --with flags
to every configure script in a large source tree without worrying about
exactly which packages want which options.  Perhaps that really is
useful for building a ton of GNU tools together, but it sure hurts
user-friendliness otherwise.
