I think we really cannot assume anything about what exactly will happen with
regard to the calling convention, which is what I was worried about earlier.
Within a certain calling convention, the behaviour of const is defined and will
not change.
Actually, even that is not true:

const parameters are indeed not suited to assembler routines for that reason.
Calling conventions should in principle be eternally frozen. This includes
const, because for exampe a DLL compiled in version x can be imported by a
program compiled by version y. The fact that it has happened (for whatever
reason) does not mean it is good practise.
