I had not understood configure was supposed to play with automake
generated VPATH.

So, I think I'm slowly starting to understand this VPATH stuff:
configure wants to remove it only when useless, right?  I.e., when
VPATH is just set to srcdir?  So then, I'm in favor of Derek's patch
which seems finer that the current one, and updating the Autoconf
documentation to explain exactly what happens.
