572: # Of course, Automake must honor this variable whenever it calls a

575: # depending on how configure is run. This is pretty annoying, since
576: # it makes $ac_aux_dir quite unusable in subdirectories: in the top

578: # relative path needs to be adjusted first.

583: # fails if $ac_aux_dir is absolute,
584: # fails when called from a subdirectory in a VPATH build with
585: # a relative $ac_aux_dir
586: #
587: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
588: # are both prefixed by $srcdir. In an in-source build this is usually
589: # harmless because $srcdir is '.', but things will broke when you
590: # start a VPATH build or use an absolute $srcdir.
591: #
592: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
593: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
594: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
595: # and then we would define $MISSING as
