For instance CXX=my-c++ ./configure ... could be used to change C++

It seems to know that c++ is the C++ compiler, but then uses cc anyway:

So is there an easy way to override this and always use C++ way of linking?
To do this you might need to set LD or CC to your C++ compiler. A
better way is to make your main program be C++ since that assures it
can work.
Consider that C++ exceptions can

On FreeBSD libtool can't find operator new[] because it is in C mode:

clang8 is used. cc is a C compiler, c++ is a C++ compiler.
Ok. Dunno why is not detected c++ at configure time. I'm not

How to switch libtool to the C++ mode?
Are you using expected file extensions for C++ code? Is your main
program a C++ module or a C module?

C++ code uses .cpp extension.
main programs are all in .c files.
