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