I'm not sure what you mean by "not acceptable"; it definitely is
acceptable.  However, the second and subsequent % characters aren't
treated as patterns, they're just treated as plain "%" characters.

So, they are acceptable and they aren't invalid, and so no error can be
generated.


I agree that this is not the most transparent way for this to behave,
but that's the way it's always been and every time I think about
changing it a number of people write in to tell me they have makefiles
that rely on this behavior.
