  87 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  88 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  89 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  90 #
  91 # Of course, Automake must honor this variable whenever it calls a
  92 # tool from the auxiliary directory.  The problem is that $srcdir (and
  93 # therefore $ac_aux_dir as well) can be either absolute or relative,
  94 # depending on how configure is run.  This is pretty annoying, since
  95 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  96 # source directory, any form will work fine, but in subdirectories a
  97 # relative path needs to be adjusted first.
  98 #
  99 # $ac_aux_dir/missing
 100 #    fails when called from a subdirectory if $ac_aux_dir is relative
 101 # $top_srcdir/$ac_aux_dir/missing
 102 #    fails if $ac_aux_dir is absolute,
 103 #    fails when called from a subdirectory in a VPATH build with
 104 #          a relative $ac_aux_dir
 105 #
 106 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 107 # are both prefixed by $srcdir.  In an in-source build this is usually
 108 # harmless because $srcdir is '.', but things will broke when you
 109 # start a VPATH build or use an absolute $srcdir.
 110 #
 111 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 112 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 113 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 114 # and then we would define $MISSING as
 115 #   MISSING="\${SHELL} $am_aux_dir/missing"
 116 # This will work as long as MISSING is not called from configure, because
 117 # unfortunately $(top_srcdir) has no meaning in configure.
 118 # However there are other variables, like CC, which are often used in
 119 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 120 #
 121 # Another solution, used here, is to always expand $ac_aux_dir to an
 122 # absolute PATH.  The drawback is that using absolute paths prevent a
 123 # configured tree to be moved without reconfiguration.
