Yes, thanks.  We'll be incorporating the C++ interface more fully into the
next release, but it may still be labeled "experimental", depending on how
far I get in revising it to fit in better with C++ standard library
mechanisms.

Since the top-level Makefile is actually created by the `configure' script,
and we haven't tried to put together all the autoconf machinery to make a
`configure' script that determines whether a C++ compiler is available and
how it should be invoked, it will take some time to implement this.  As an
example of the complications involved, the configure script will have to
determine whether the C++ compiler has sufficient support for exceptions and
templates, and perhaps the code will have to use conditional compilation to
simulate these features if they are not available.

Adding 
        make c++
        make install-c++
install targets is considerably easier, so I'll probably do that first.
