    66 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

    68 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
       
    69 #
       
    70 # Of course, Automake must honor this variable whenever it calls a
       
    71 # tool from the auxiliary directory.  The problem is that $srcdir (and
       
    72 # therefore $ac_aux_dir as well) can be either absolute or relative,
       
    73 # depending on how configure is run.  This is pretty annoying, since
       
    74 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
       
    75 # source directory, any form will work fine, but in subdirectories a
       
    76 # relative path needs to be adjusted first.
       
    77 #
       
    78 # $ac_aux_dir/missing

    80 # $top_srcdir/$ac_aux_dir/missing
       
    81 #    fails if $ac_aux_dir is absolute,
       
    82 #    fails when called from a subdirectory in a VPATH build with
       
    83 #          a relative $ac_aux_dir
       
    84 #
       
    85 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
       
    86 # are both prefixed by $srcdir.  In an in-source build this is usually
       
    87 # harmless because $srcdir is `.', but things will broke when you
       
    88 # start a VPATH build or use an absolute $srcdir.
       
    89 #
       
    90 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
       
    91 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
       
    92 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
       
    93 # and then we would define $MISSING as
       
    94 #   MISSING="\${SHELL} $am_aux_dir/missing"
       
    95 # This will work as long as MISSING is not called from configure, because
       
    96 # unfortunately $(top_srcdir) has no meaning in configure.
       
    97 # However there are other variables, like CC, which are often used in
       
    98 # configure, and could therefore not use this "fixed" $ac_aux_dir.
       
    99 #
       
   100 # Another solution, used here, is to always expand $ac_aux_dir to an
       
   101 # absolute PATH.  The drawback is that using absolute paths prevent a
