504     # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
505     # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
506     # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
507     #
508     # Of course, Automake must honor this variable whenever it calls a
509     # tool from the auxiliary directory. The problem is that $srcdir (and
510     # therefore $ac_aux_dir as well) can be either absolute or relative,
511     # depending on how configure is run. This is pretty annoying, since
512     # it makes $ac_aux_dir quite unusable in subdirectories: in the top
513     # source directory, any form will work fine, but in subdirectories a
514     # relative path needs to be adjusted first.
515     #
516     # $ac_aux_dir/missing
517     # fails when called from a subdirectory if $ac_aux_dir is relative
518     # $top_srcdir/$ac_aux_dir/missing
519     # fails if $ac_aux_dir is absolute,
520     # fails when called from a subdirectory in a VPATH build with
521     # a relative $ac_aux_dir
522     #
523     # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
524     # are both prefixed by $srcdir. In an in-source build this is usually
525     # harmless because $srcdir is `.', but things will broke when you
526     # start a VPATH build or use an absolute $srcdir.
527     #
528     # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
529     # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
530     # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
531     # and then we would define $MISSING as
532     # MISSING="\${SHELL} $am_aux_dir/missing"
533     # This will work as long as MISSING is not called from configure, because
534     # unfortunately $(top_srcdir) has no meaning in configure.
535     # However there are other variables, like CC, which are often used in
536     # configure, and could therefore not use this "fixed" $ac_aux_dir.
537     #
538     # Another solution, used here, is to always expand $ac_aux_dir to an
539     # absolute PATH. The drawback is that using absolute paths prevent a
540     # configured tree to be moved without reconfiguration.
