  125 
  126 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  127 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  128 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  129 #
  130 # Of course, Automake must honor this variable whenever it calls a
  131 # tool from the auxiliary directory.  The problem is that $srcdir (and
  132 # therefore $ac_aux_dir as well) can be either absolute or relative,
  133 # depending on how configure is run.  This is pretty annoying, since
  134 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  135 # source directory, any form will work fine, but in subdirectories a
  136 # relative path needs to be adjusted first.
  137 #
  138 # $ac_aux_dir/missing
  139 #    fails when called from a subdirectory if $ac_aux_dir is relative
  140 # $top_srcdir/$ac_aux_dir/missing
  141 #    fails if $ac_aux_dir is absolute,
  142 #    fails when called from a subdirectory in a VPATH build with
  143 #          a relative $ac_aux_dir
  144 #
  145 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  146 # are both prefixed by $srcdir.  In an in-source build this is usually
  147 # harmless because $srcdir is '.', but things will broke when you
  148 # start a VPATH build or use an absolute $srcdir.
  149 #
  150 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  151 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  152 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  153 # and then we would define $MISSING as
  154 #   MISSING="\${SHELL} $am_aux_dir/missing"
  155 # This will work as long as MISSING is not called from configure, because
  156 # unfortunately $(top_srcdir) has no meaning in configure.
  157 # However there are other variables, like CC, which are often used in
  158 # configure, and could therefore not use this "fixed" $ac_aux_dir.
  159 #
  160 # Another solution, used here, is to always expand $ac_aux_dir to an
  161 # absolute PATH.  The drawback is that using absolute paths prevent a
  162 # configured tree to be moved without reconfiguration.
