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

    907 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
    908 #
    909 # Of course, Automake must honor this variable whenever it calls a
    910 # tool from the auxiliary directory.  The problem is that $srcdir (and
    911 # therefore $ac_aux_dir as well) can be either absolute or relative,
    912 # depending on how configure is run.  This is pretty annoying, since
    913 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
    914 # source directory, any form will work fine, but in subdirectories a
    915 # relative path needs to be adjusted first.
    916 #
    917 # $ac_aux_dir/missing

    919 # $top_srcdir/$ac_aux_dir/missing
    920 #    fails if $ac_aux_dir is absolute,
    921 #    fails when called from a subdirectory in a VPATH build with
    922 #          a relative $ac_aux_dir
    923 #
    924 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
    925 # are both prefixed by $srcdir.  In an in-source build this is usually
    926 # harmless because $srcdir is '.', but things will broke when you
    927 # start a VPATH build or use an absolute $srcdir.
    928 #
    929 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
    930 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
    931 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
    932 # and then we would define $MISSING as
    933 #   MISSING="\${SHELL} $am_aux_dir/missing"
    934 # This will work as long as MISSING is not called from configure, because
    935 # unfortunately $(top_srcdir) has no meaning in configure.
    936 # However there are other variables, like CC, which are often used in
    937 # configure, and could therefore not use this "fixed" $ac_aux_dir.
    938 #
    939 # Another solution, used here, is to always expand $ac_aux_dir to an
    940 # absolute PATH.  The drawback is that using absolute paths prevent a
