Well, I was referring to such kind of situations:

* A top level configure-script accessing several config-subdirs:

# cat configure.ac
..
AC_CONFIG_AUX_DIR(.)
..
AC_CONFIG_SUBDIRS(sub1 sub2 sub3)
..

* With each subN/configure.ac containing:
# cat sub1/configure.ac
...
AC_CONFIG_AUX_DIR(..)
..

or not explicitly setting AC_CONFIG_AUX_DIR
 
=> All subN/configure.acs and configure.ac will share <toplevel> as
config-auxdir.
 
This had worked for ages (It is the default behavior).

And yes, I am using it.

Yes, a "subdir" 'make dist' in most cases doesn't work, but a "toplevel"
'make dist' normally does.

Agreed.

Exactly.
