398 # Of course, Automake must honor this variable whenever it calls a
399 # tool from the auxiliary directory. The problem is that $srcdir (and
400 # therefore $ac_aux_dir as well) can be either absolute or relative,
401 # depending on how configure is run. This is pretty annoying, since
402 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
403 # source directory, any form will work fine, but in subdirectories a
404 # relative path needs to be adjusted first.

409 # fails if $ac_aux_dir is absolute,
410 # fails when called from a subdirectory in a VPATH build with
411 # a relative $ac_aux_dir
413 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
414 # are both prefixed by $srcdir. In an in-source build this is usually
415 # harmless because $srcdir is `.', but things will broke when you
416 # start a VPATH build or use an absolute $srcdir.
418 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
419 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
420 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
421 # and then we would define $MISSING as
422 # MISSING="\${SHELL} $am_aux_dir/missing"
423 # This will work as long as MISSING is not called from configure, because
424 # unfortunately $(top_srcdir) has no meaning in configure.
425 # However there are other variables, like CC, which are often used in
426 # configure, and could therefore not use this "fixed" $ac_aux_dir.
428 # Another solution, used here, is to always expand $ac_aux_dir to an
