  67 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  68 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  69 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  70 #
  71 # Of course, Automake must honor this variable whenever it calls a
  72 # tool from the auxiliary directory.  The problem is that $srcdir (and
  73 # therefore $ac_aux_dir as well) can be either absolute or relative,
  74 # depending on how configure is run.  This is pretty annoying, since
  75 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  76 # source directory, any form will work fine, but in subdirectories a
  77 # relative path needs to be adjusted first.
  78 #
  79 # $ac_aux_dir/missing
  80 #    fails when called from a subdirectory if $ac_aux_dir is relative
  81 # $top_srcdir/$ac_aux_dir/missing
  82 #    fails if $ac_aux_dir is absolute,
  83 #    fails when called from a subdirectory in a VPATH build with
  84 #          a relative $ac_aux_dir
  85 #
  86 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  87 # are both prefixed by $srcdir.  In an in-source build this is usually
  88 # harmless because $srcdir is '.', but things will broke when you
  89 # start a VPATH build or use an absolute $srcdir.
  90 #
  91 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  92 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  93 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  94 # and then we would define $MISSING as
  95 #   MISSING="\${SHELL} $am_aux_dir/missing"
  96 # This will work as long as MISSING is not called from configure, because
  97 # unfortunately $(top_srcdir) has no meaning in configure.
  98 # However there are other variables, like CC, which are often used in
  99 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 100 #
 101 # Another solution, used here, is to always expand $ac_aux_dir to an
 102 # absolute PATH.  The drawback is that using absolute paths prevent a
 103 # configured tree to be moved without reconfiguration.
