6440 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6441 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
6442 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6443 #
6444 # Of course, Automake must honor this variable whenever it calls a
6445 # tool from the auxiliary directory.  The problem is that $srcdir (and
6446 # therefore $ac_aux_dir as well) can be either absolute or relative,
6447 # depending on how configure is run.  This is pretty annoying, since
6448 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
6449 # source directory, any form will work fine, but in subdirectories a
6450 # relative path needs to be adjusted first.
6451 #
6452 # $ac_aux_dir/missing
6453 #    fails when called from a subdirectory if $ac_aux_dir is relative
6454 # $top_srcdir/$ac_aux_dir/missing
6455 #    fails if $ac_aux_dir is absolute,
6456 #    fails when called from a subdirectory in a VPATH build with
6457 #          a relative $ac_aux_dir
6458 #
6459 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6460 # are both prefixed by $srcdir.  In an in-source build this is usually
6461 # harmless because $srcdir is `.', but things will broke when you
6462 # start a VPATH build or use an absolute $srcdir.
6463 #
6464 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6465 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6466 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6467 # and then we would define $MISSING as
6468 #   MISSING="\${SHELL} $am_aux_dir/missing"
6469 # This will work as long as MISSING is not called from configure, because
6470 # unfortunately $(top_srcdir) has no meaning in configure.
6471 # However there are other variables, like CC, which are often used in
6472 # configure, and could therefore not use this "fixed" $ac_aux_dir.
6473 #
6474 # Another solution, used here, is to always expand $ac_aux_dir to an
6475 # absolute PATH.  The drawback is that using absolute paths prevent a
