  145 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  146 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  147 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  148 #
  149 # Of course, Automake must honor this variable whenever it calls a
  150 # tool from the auxiliary directory.  The problem is that $srcdir (and
  151 # therefore $ac_aux_dir as well) can be either absolute or relative,
  152 # depending on how configure is run.  This is pretty annoying, since
  153 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  154 # source directory, any form will work fine, but in subdirectories a
  155 # relative path needs to be adjusted first.
  156 #
  157 # $ac_aux_dir/missing
  158 #    fails when called from a subdirectory if $ac_aux_dir is relative
  159 # $top_srcdir/$ac_aux_dir/missing
  160 #    fails if $ac_aux_dir is absolute,
  161 #    fails when called from a subdirectory in a VPATH build with
  162 #          a relative $ac_aux_dir
  163 #
  164 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  165 # are both prefixed by $srcdir.  In an in-source build this is usually
  166 # harmless because $srcdir is '.', but things will broke when you
  167 # start a VPATH build or use an absolute $srcdir.
  168 #
  169 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  170 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  171 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  172 # and then we would define $MISSING as
  173 #   MISSING="\${SHELL} $am_aux_dir/missing"
  174 # This will work as long as MISSING is not called from configure, because
  175 # unfortunately $(top_srcdir) has no meaning in configure.
  176 # However there are other variables, like CC, which are often used in
  177 # configure, and could therefore not use this "fixed" $ac_aux_dir.
  178 #
  179 # Another solution, used here, is to always expand $ac_aux_dir to an
  180 # absolute PATH.  The drawback is that using absolute paths prevent a
  181 # configured tree to be moved without reconfiguration.
