[PATCH 0/2] Tests initialization: put default definition of AC_CONFIG_AUX_DIR in the pre-populated configure.in.

[Stefano Lattarini]

This is a reproposal of an older patch of mine:
 <http://lists.gnu.org/archive/html/automake-patches/2010-05/msg00008.html>
 <http://lists.gnu.org/archive/html/automake-patches/2010-05/msg00009.html>

Hello automakers.

I see that some tests explicitly put a call like:
  AC_CONFIG_AUX_DIR([.])
in the generated configure.in, to prevent automake from looking into
`..' and `../..' when trying to copy required files.

I think that such a provision should be made unconditional, as it could
help to reduce undefined/unexpected behaviours.  Obviously, we should
leave a way for the individual testcases to easily override this default
(and some existing tests already require such an overriding).

The first patch in this series implements this idea.  The second one 
extends the tests on `AC_CONFIG_AUX_DIR' itself.

OK to apply the patches to a temporary branch off of maint, and merge
to the tests-init branch?  I'll wait the customary 72 hours (until
Tuesday evening) before pushing.

Regards,
  Stefano
