  # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  #
  # Of course, Automake must honor this variable whenever it calls a
  # tool from the auxiliary directory.  The problem is that $srcdir (and
  # therefore $ac_aux_dir as well) can be either absolute or relative,
  # depending on how configure is run.  This is pretty annoying, since
  # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  # source directory, any form will work fine, but in subdirectories a
  # relative path needs to be adjusted first.
  #
  # $ac_aux_dir/missing
  #    fails when called from a subdirectory if $ac_aux_dir is relative
  # $top_srcdir/$ac_aux_dir/missing
  #    fails if $ac_aux_dir is absolute,
  #    fails when called from a subdirectory in a VPATH build with
  #          a relative $ac_aux_dir
  #
  # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  # are both prefixed by $srcdir.  In an in-source build this is usually
  # harmless because $srcdir is '.', but things will broke when you
  # start a VPATH build or use an absolute $srcdir.
  #
  # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  # and then we would define $MISSING as
  #   MISSING="\${SHELL} $am_aux_dir/missing"
  # This will work as long as MISSING is not called from configure, because
  # unfortunately $(top_srcdir) has no meaning in configure.
  # However there are other variables, like CC, which are often used in
  # configure, and could therefore not use this "fixed" $ac_aux_dir.
  #
  # Another solution, used here, is to always expand $ac_aux_dir to an
  # absolute PATH.  The drawback is that using absolute paths prevent a
  # configured tree to be moved without reconfiguration.
