  According to it, you should have just one in top level

  used, but for a new project today this should be avoided.  It just
  slows things down and leads to unneeded compiler calls.

I'm sorry, but where on earth did you get this terrible information?

A per directory is precisly what should be used, it
doesn't incure any extra compiler calls.  It also makes it easy to
build seperate parts of the tree.

There is an existing paper about this argument. This is exactly addressed in the automake documentation, and automake supports that single-directory method if you so choose. I can find the reference for you in a few hours.

I do note that this is the autoconf list, not automake. I don't see a crosspost.
