What I wanted to say is that it would be great if Autoconf and Automake
were consistent wrt to language mixing.  I have no idea whether your
objections are right or not (and I did not remember telling anything
about C++), but please read Automake documentation about this topic, you
will understand my confusion concerning current detection scheme.
