544: #
545: # Of course, Automake must honor this variable whenever it calls a
546: # tool from the auxiliary directory. The problem is that $srcdir (and
547: # therefore $ac_aux_dir as well) can be either absolute or relative,
548: # depending on how configure is run. This is pretty annoying, since
549: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
550: # source directory, any form will work fine, but in subdirectories a
551: # relative path needs to be adjusted first.
552: #
553: # $ac_aux_dir/missing
554: # fails when called from a subdirectory if $ac_aux_dir is relative
555: # $top_srcdir/$ac_aux_dir/missing
556: # fails if $ac_aux_dir is absolute,
557: # fails when called from a subdirectory in a VPATH build with
558: # a relative $ac_aux_dir
559: #
560: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
561: # are both prefixed by $srcdir. In an in-source build this is usually
562: # harmless because $srcdir is '.', but things will broke when you
563: # start a VPATH build or use an absolute $srcdir.
564: #
565: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
566: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
567: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
568: # and then we would define $MISSING as
569: # MISSING="\${SHELL} $am_aux_dir/missing"
570: # This will work as long as MISSING is not called from configure, because
571: # unfortunately $(top_srcdir) has no meaning in configure.
572: # However there are other variables, like CC, which are often used in
573: # configure, and could therefore not use this "fixed" $ac_aux_dir.
574: #
575: # Another solution, used here, is to always expand $ac_aux_dir to an
