This is working just fine. In the make file, it first compiles each file 
seperately (gxx -c -O2 demo.cc). The '-c' option comples that file to an 
object file (demo.o), not to an executable file (demo.exe). Only after all 
the files all compiled into object files are they linked together into an 
executable file. The messages (above) that you are getting are just 
telling you that the linker isn't being used for that particular 
compilation (whenever the '-c' option is used). They are not error 
messages and are nothing to worry about. In fact, that is what should happen.
