So far so good...

That's a bit unclear to me.

Having only foo_<system>.cxx would be clear. ;-)
This way works too if you generate correct linking for every case. It starts 
to get worse when there are different targets that differ only slightly. I 
could imagine that I'd have e.g.:
System <-- SystemLinux <-- SystemFreeBSD as a class hierachie for Strategy if 
FreeBSD is very similar to Linux and needs only a slightly different 
approach. Doing this with differnt files requires to duplicate all the code 
instead of simply overloading one or two virtual functions.
