  227 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  228 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  229 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  230 #
  231 # Of course, Automake must honor this variable whenever it calls a
  232 # tool from the auxiliary directory.  The problem is that $srcdir (and
  233 # therefore $ac_aux_dir as well) can be either absolute or relative,
  234 # depending on how configure is run.  This is pretty annoying, since
  235 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  236 # source directory, any form will work fine, but in subdirectories a
  237 # relative path needs to be adjusted first.
  238 #
  239 # $ac_aux_dir/missing
  240 #    fails when called from a subdirectory if $ac_aux_dir is relative
  241 # $top_srcdir/$ac_aux_dir/missing
  242 #    fails if $ac_aux_dir is absolute,
  243 #    fails when called from a subdirectory in a VPATH build with
  244 #          a relative $ac_aux_dir
  245 #
  246 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  247 # are both prefixed by $srcdir.  In an in-source build this is usually
  248 # harmless because $srcdir is '.', but things will broke when you
  249 # start a VPATH build or use an absolute $srcdir.
  250 #
  251 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  252 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  253 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  254 # and then we would define $MISSING as
  255 #   MISSING="\${SHELL} $am_aux_dir/missing"
  256 # This will work as long as MISSING is not called from configure, because
  257 # unfortunately $(top_srcdir) has no meaning in configure.
  258 # However there are other variables, like CC, which are often used in
  259 # configure, and could therefore not use this "fixed" $ac_aux_dir.
  260 #
  261 # Another solution, used here, is to always expand $ac_aux_dir to an
  262 # absolute PATH.  The drawback is that using absolute paths prevent a
  263 # configured tree to be moved without reconfiguration.
