At a minimum, the following section of src/CMD/generic/gmake.sh would
need to be extended to allow for creating a .o file from a .cc file.

	    while read file
	    do
		if test -f $file.f
		then
		    echo '$(OBJARCH)/'${file}.o: ${file}.f
	#	    echo '	rm -f $@'
	#	    echo '	$(FC) $(FFLAGS) -c' ${file}.f
	#	    echo '	mv' ${file}.o '$@'
	# new version MN:
		    echo '	$(FC) $(FFLAGS) -c' ${file}.f -o '$@'
		else
		    echo '$(OBJARCH)/'${file}.o: ${file}.c
	#	    echo '	rm -f $@'
	#	    echo '	$(CC) $(CFLAGS) -c' ${file}.c
	#	    echo '	mv' ${file}.o '$@'
	# new version MN:
		    echo '	$(CC) $(CFLAGS) -c' ${file}.c -o '$@'
		fi
	    done
