Indeed you are exactly right. My comment was because in the patch you
sent there was some code to initialize the automatic variables for
target A if there was a reference to $(A::var). I don't think that this
code is necessary, or even a good idea. If the automatic variables are
not initialized for A, then expanding $(A::<) (etc.) should yield the
empty string, just like $< etc.
Or, am I missing something?
