I used the example from the book, and tried to reproduce this multiple defined symbols issue in different ways, and didn't succeed. I understand that real projects are much more complicated than the examples, though; so some combination of settings may result in this conflict.
If you could provide the full build log of your application (with all compiler and linker options shown), together with some additional info about what file(s) you put the replacing operators into (parallelspatialattributes.cpp I guess; only into this one?), there might be some ideas arising about what's caused the error.
As far as I remember, /FORCE option passed to the linker should shut it down in cases of multiple and unresolved symbols; but I would count on this as the last resort only.
