I fail to understand how your answer helps anyone.

Currently, 'autoconf' fails and 'autoconf -I../config' succeeds.
With the change, both would succeed and be equivalent.
What is the benefit of requiring a command-line option when the only possible
value can be provided as a default?

I am using 
# autoreconf $(computed list of subdirectories)
This would be way more difficult if I had to add a different -I option for each
subdirectory.
