1463 # Of course, Automake must honor this variable whenever it calls a

1465 # therefore $ac_aux_dir as well) can be either absolute or relative,
1466 # depending on how configure is run. This is pretty annoying, since
1467 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
1468 # source directory, any form will work fine, but in subdirectories a
1469 # relative path needs to be adjusted first.

1474 # fails if $ac_aux_dir is absolute,
1475 # fails when called from a subdirectory in a VPATH build with
1476 # a relative $ac_aux_dir
1478 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1479 # are both prefixed by $srcdir. In an in-source build this is usually
1480 # harmless because $srcdir is '.', but things will broke when you
1481 # start a VPATH build or use an absolute $srcdir.
1483 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1484 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
1485 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1486 # and then we would define $MISSING as
1487 # MISSING="\${SHELL} $am_aux_dir/missing"
1488 # This will work as long as MISSING is not called from configure, because
1489 # unfortunately $(top_srcdir) has no meaning in configure.
1490 # However there are other variables, like CC, which are often used in
