! 363: #
! 364: # Of course, Automake must honor this variable whenever it calls a

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

! 378: #
! 379: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir

! 381: # harmless because $srcdir is `.', but things will broke when you
! 382: # start a VPATH build or use an absolute $srcdir.
! 383: #
! 384: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
! 385: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
! 386: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

! 392: # configure, and could therefore not use this "fixed" $ac_aux_dir.
! 393: #
