- Why not look at H/W as "dynamic-linked shared libraries" that is bound

- But the problem is that the one must have thought of checking for all
- the different combinations at the time before generating the binary. If
- binary compatibility is important, the binaries that the system must
- run whill have been generating with none of the checks. (Murphy's law
- says binaries that you don't care about will have all possible checks
- already present, but you could just easily rebuilt them).
