There are at least two C++ compilers (MSVC and a native OS/390 one)
which can't handle the `.cc' extension, while *all* C++ compilers can
handle `.cpp'.

Whether `make' programs recognize the `.cpp' extension by default is
completely irrelevant for autoconf. BTW, groff's Makefiles don't use
*any* built-in make rules.
