    The version of g++ distributed with InterViews is a snapshot
    that works with our code.  I'm not sure about the g++ 1.35.0 compiler,
    but there were fixes needed to g++ in the process of getting it to work
    with InterViews (as well as vice versa).

    The InterViews distribution contains its own set of header files and
    a stream implementation, thereby making the code functional
    with either g++ or cfront.  The distribution does not include libg++;
    we provide a CC command that works with either c++ (g++'s compiler) or
    cfront.  Unlike the g++ compiler driver, our CC command does not
    try to link with libg++.

    My intent in all of this is to satisfy all of the following needs:

	(1) People who want to use InterViews with cfront.
	(2) People who want to use InterViews with standard g++.
	(3) People who don't have a C++ compiler, but want to try InterViews.

    I'm sure (1) and (3) work, as I have tested them.  As we don't use libg++
    here, I haven't tested (2).  If there are problems using standard g++
    that are not 1.35.0 bugs, I would like to know about them.
