441: #
442: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
443: # are both prefixed by $srcdir. In an in-source build this is usually
444: # harmless because $srcdir is `.', but things will broke when you
445: # start a VPATH build or use an absolute $srcdir.
446: #
447: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
448: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
449: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
450: # and then we would define $MISSING as
451: # MISSING="\${SHELL} $am_aux_dir/missing"
452: # This will work as long as MISSING is not called from configure, because
453: # unfortunately $(top_srcdir) has no meaning in configure.
