Hi,

  Your previous bugs indicated that we needed to call autoreconf all the
time.  A side effect was that the auto scale-back of calling the
miscellaneous autoconf features was removed.

I would guess that there is some simple algorithm that could be used,
but I don't know what it might be as I haven't looked into it much.

We could also make it the responsibility of the user to choose which
kind of compile to do.
