  127: # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  128: # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  129: # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  130: #
  131: # Of course, Automake must honor this variable whenever it calls a
  132: # tool from the auxiliary directory.  The problem is that $srcdir (and
  133: # therefore $ac_aux_dir as well) can be either absolute or relative,
  134: # depending on how configure is run.  This is pretty annoying, since
  135: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  136: # source directory, any form will work fine, but in subdirectories a
  137: # relative path needs to be adjusted first.
  138: #
  139: # $ac_aux_dir/missing
  140: #    fails when called from a subdirectory if $ac_aux_dir is relative
  141: # $top_srcdir/$ac_aux_dir/missing
  142: #    fails if $ac_aux_dir is absolute,
  143: #    fails when called from a subdirectory in a VPATH build with
  144: #          a relative $ac_aux_dir
  145: #
  146: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  147: # are both prefixed by $srcdir.  In an in-source build this is usually
  148: # harmless because $srcdir is '.', but things will broke when you
  149: # start a VPATH build or use an absolute $srcdir.
  150: #
  151: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  152: # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  153: #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  154: # and then we would define $MISSING as
  155: #   MISSING="\${SHELL} $am_aux_dir/missing"
  156: # This will work as long as MISSING is not called from configure, because
  157: # unfortunately $(top_srcdir) has no meaning in configure.
  158: # However there are other variables, like CC, which are often used in
  159: # configure, and could therefore not use this "fixed" $ac_aux_dir.
  160: #
  161: # Another solution, used here, is to always expand $ac_aux_dir to an
  162: # absolute PATH.  The drawback is that using absolute paths prevent a
  163: # configured tree to be moved without reconfiguration.
