1421 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

1423 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
1425 # Of course, Automake must honor this variable whenever it calls a

1427 # therefore $ac_aux_dir as well) can be either absolute or relative,
1428 # depending on how configure is run. This is pretty annoying, since
1429 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
1430 # source directory, any form will work fine, but in subdirectories a
1431 # relative path needs to be adjusted first.

1436 # fails if $ac_aux_dir is absolute,
1437 # fails when called from a subdirectory in a VPATH build with
1438 # a relative $ac_aux_dir
1440 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1441 # are both prefixed by $srcdir. In an in-source build this is usually
1442 # harmless because $srcdir is `.', but things will broke when you
1443 # start a VPATH build or use an absolute $srcdir.
1445 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1446 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
1447 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1448 # and then we would define $MISSING as
1449 # MISSING="\${SHELL} $am_aux_dir/missing"
1450 # This will work as long as MISSING is not called from configure, because
1451 # unfortunately $(top_srcdir) has no meaning in configure.
1452 # However there are other variables, like CC, which are often used in
1453 # configure, and could therefore not use this "fixed" $ac_aux_dir.
