6457 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6458 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
6459 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6460 #
6461 # Of course, Automake must honor this variable whenever it calls a
6462 # tool from the auxiliary directory.  The problem is that $srcdir (and
6463 # therefore $ac_aux_dir as well) can be either absolute or relative,
6464 # depending on how configure is run.  This is pretty annoying, since
6465 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
6466 # source directory, any form will work fine, but in subdirectories a
6467 # relative path needs to be adjusted first.
6468 #
6469 # $ac_aux_dir/missing
6470 #    fails when called from a subdirectory if $ac_aux_dir is relative
6471 # $top_srcdir/$ac_aux_dir/missing
6472 #    fails if $ac_aux_dir is absolute,
6473 #    fails when called from a subdirectory in a VPATH build with
6474 #          a relative $ac_aux_dir
6475 #
6476 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6477 # are both prefixed by $srcdir.  In an in-source build this is usually
6478 # harmless because $srcdir is `.', but things will broke when you
6479 # start a VPATH build or use an absolute $srcdir.
6480 #
6481 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6482 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6483 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6484 # and then we would define $MISSING as
6485 #   MISSING="\${SHELL} $am_aux_dir/missing"
6486 # This will work as long as MISSING is not called from configure, because
6487 # unfortunately $(top_srcdir) has no meaning in configure.
6488 # However there are other variables, like CC, which are often used in
6489 # configure, and could therefore not use this "fixed" $ac_aux_dir.
6490 #
6491 # Another solution, used here, is to always expand $ac_aux_dir to an
6492 # absolute PATH.  The drawback is that using absolute paths prevent a
