At least working with 7.15.5 I was able to do work. I checked out
from the CVS about an hour ago. Install automake 1.7, because it
didn't like automake 1.6. Now I am getting this error

m4_pattern_allow.

In theory there is no difference between theory and practice.
In practice there is no similarity.
