Why namespace freebsd?
Only one version of GetRealFunctionAddress should exist, which is enforced by #ifdef __FreeBSD__, etc.
If this enforcement breaks, we'll get GetRealFunctionAddress and freebsd::GetRealFunctionAddress, which is a mess. 
I'd prefer to not introduce "namespace freebsd" or at least add a comment why you need one here.

doesn't "weak" work on FeeBSD? (just curious)
