  247: # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

  249: # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  250: #
  251: # Of course, Automake must honor this variable whenever it calls a
  252: # tool from the auxiliary directory.  The problem is that $srcdir (and
  253: # therefore $ac_aux_dir as well) can be either absolute or relative,
  254: # depending on how configure is run.  This is pretty annoying, since
  255: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  256: # source directory, any form will work fine, but in subdirectories a
  257: # relative path needs to be adjusted first.
  258: #
  259: # $ac_aux_dir/missing
  260: #    fails when called from a subdirectory if $ac_aux_dir is relative
  261: # $top_srcdir/$ac_aux_dir/missing
  262: #    fails if $ac_aux_dir is absolute,
  263: #    fails when called from a subdirectory in a VPATH build with
  264: #          a relative $ac_aux_dir
  265: #
  266: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  267: # are both prefixed by $srcdir.  In an in-source build this is usually
  268: # harmless because $srcdir is `.', but things will broke when you
  269: # start a VPATH build or use an absolute $srcdir.
  270: #
  271: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  272: # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  273: #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  274: # and then we would define $MISSING as
  275: #   MISSING="\${SHELL} $am_aux_dir/missing"
  276: # This will work as long as MISSING is not called from configure, because
  277: # unfortunately $(top_srcdir) has no meaning in configure.
  278: # However there are other variables, like CC, which are often used in
  279: # configure, and could therefore not use this "fixed" $ac_aux_dir.
  280: #
  281: # Another solution, used here, is to always expand $ac_aux_dir to an
