gxx is simply a wrapper for gcc that adds the standard C++ libraries to
the end of the command line, and then invokes gcc.  The problem is that,
when you do this in conjunction with the '-c' switch, you are telling
gcc to produce object code output, but also specifying libraries to link
on the command line.  Obviously, since the linker is never called,
nothing is done with the libraries, but gcc tells you this in case you
didn't realize it.

gxx is only needed when _linking_ C++ programs, or when compiling and
linking simultaneously.  In that makefile, you should use gcc to
compile, and use gxx only when linking the final executable.
