     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
