! 270: #
! 271: # Of course, Automake must honor this variable whenever it calls a

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

! 283: # fails when called from a subdirectory in a VPATH build with

! 285: #
! 286: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
! 287: # are both prefixed by $srcdir. In an in-source build this is usually
! 288: # harmless because $srcdir is '.', but things will broke when you
! 289: # start a VPATH build or use an absolute $srcdir.
! 290: #
! 291: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
! 292: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
! 293: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
