Fix a bug where the Mercury calls C++ sample was not linking with the
C++ library. This worked, because the sample didn't actually make use
of the C++ library, but failed as soon as users tried to extend the
sample to use with their real C++ programs.
samples/c_interface/mercury_calls_cplusplus/cpp_main.cc:
Use the C++ standard library's stream I/O, rather than printf().
samples/c_interface/mercury_calls_cplusplus/Mmakefile:
Make sure that we link with the C++ standard library.
Also, comment out the old hack that worked around a g++ 2.7 bug
which is fixed in g++ 2.95.

Fix a bug where the Mercury calls C++ sample was actually using C, not C++.
samples/c_interface/mercury_calls_cplusplus/cpp_main.c:
samples/c_interface/mercury_calls_cplusplus/cpp_main.cc:
Rename cpp_main.c as cpp_main.cc, so that it gets compiled as C++
code rather than as C code. Add a dummy class declaration to its
source, to check that it is really C++ code.
