1470 # Of course, Automake must honor this variable whenever it calls a

1473 # depending on how configure is run. This is pretty annoying, since
1474 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
1475 # source directory, any form will work fine, but in subdirectories a
1476 # relative path needs to be adjusted first.

1485 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1486 # are both prefixed by $srcdir. In an in-source build this is usually
1487 # harmless because $srcdir is '.', but things will broke when you
1488 # start a VPATH build or use an absolute $srcdir.
1490 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

1492 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
