    424 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
    425 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
    426 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
    427 #
    428 # Of course, Automake must honor this variable whenever it calls a
    429 # tool from the auxiliary directory.  The problem is that $srcdir (and
    430 # therefore $ac_aux_dir as well) can be either absolute or relative,
    431 # depending on how configure is run.  This is pretty annoying, since
    432 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
    433 # source directory, any form will work fine, but in subdirectories a
    434 # relative path needs to be adjusted first.
    435 #
    436 # $ac_aux_dir/missing
    437 #    fails when called from a subdirectory if $ac_aux_dir is relative
    438 # $top_srcdir/$ac_aux_dir/missing
    439 #    fails if $ac_aux_dir is absolute,
    440 #    fails when called from a subdirectory in a VPATH build with
    441 #          a relative $ac_aux_dir
    442 #
    443 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
    444 # are both prefixed by $srcdir.  In an in-source build this is usually
    445 # harmless because $srcdir is '.', but things will broke when you
    446 # start a VPATH build or use an absolute $srcdir.
    447 #
    448 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
    449 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
    450 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
    451 # and then we would define $MISSING as
    452 #   MISSING="\${SHELL} $am_aux_dir/missing"
    453 # This will work as long as MISSING is not called from configure, because
    454 # unfortunately $(top_srcdir) has no meaning in configure.
    455 # However there are other variables, like CC, which are often used in
    456 # configure, and could therefore not use this "fixed" $ac_aux_dir.
    457 #
    458 # Another solution, used here, is to always expand $ac_aux_dir to an
    459 # absolute PATH.  The drawback is that using absolute paths prevent a
    460 # configured tree to be moved without reconfiguration.
