Which is not really a great assumption since C++ is a different language and the C++ compiler vendor may not be the same as the C compiler vendor. The behavior of the C++ preprocessing may behave differently. Autoconf and Automake make a lot of assumptions when it comes to C++. Luckily the assumptions are correct more often than not.
