  94 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  95 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
  96 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  97 #
  98 # Of course, Automake must honor this variable whenever it calls a
  99 # tool from the auxiliary directory.  The problem is that $srcdir (and
 100 # therefore $ac_aux_dir as well) can be either absolute or relative,
 101 # depending on how configure is run.  This is pretty annoying, since
 102 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 103 # source directory, any form will work fine, but in subdirectories a
 104 # relative path needs to be adjusted first.
 105 #
 106 # $ac_aux_dir/missing
 107 #    fails when called from a subdirectory if $ac_aux_dir is relative
 108 # $top_srcdir/$ac_aux_dir/missing
 109 #    fails if $ac_aux_dir is absolute,
 110 #    fails when called from a subdirectory in a VPATH build with
 111 #          a relative $ac_aux_dir
 112 #
 113 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 114 # are both prefixed by $srcdir.  In an in-source build this is usually
 115 # harmless because $srcdir is `.', but things will broke when you
 116 # start a VPATH build or use an absolute $srcdir.
 117 #
 118 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 119 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 120 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 121 # and then we would define $MISSING as
 122 #   MISSING="\${SHELL} $am_aux_dir/missing"
 123 # This will work as long as MISSING is not called from configure, because
 124 # unfortunately $(top_srcdir) has no meaning in configure.
 125 # However there are other variables, like CC, which are often used in
 126 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 127 #
 128 # Another solution, used here, is to always expand $ac_aux_dir to an
 129 # absolute PATH.  The drawback is that using absolute paths prevent a
 130 # configured tree to be moved without reconfiguration.
