Sorry, I don't get the connection here.  The extension in question is
used to do things like have "configure" invoke "CC conftest.cpp"; it
isn't used for Makefiles, as far as I know.

It would be nice to determine the C++ extension automatically, I
suppose.  Failing that, a documented approach along the lines that you
suggest would be OK, if it's needed.  Is it needed?  If so, can you
propose a patch along those lines?
