    66  # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
    67  # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
    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
    79  #    fails when called from a subdirectory if $ac_aux_dir is relative
    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
