Ok, that's good.  But if the user defines a variable conditionally
then automake should still be able to define it when the condition
does not hold.

Akim> What are the ideal rules we'd like to have?

As much as possible variable assignments should work as the user
"expects".

Mostly we did ok here.  But there were cases where we didn't.  For
instance this didn't used to work:

    foo = whatever
    if COND
    foo += something else
    endif
