The same specification (re storage class for func arguments) is made
in K&R Appendix section 10.1, where it means nothing of the sort.

[ I don't have an ANSI draft, but if the above section is your only
support, you must be mistaken ]

I would think it would be up to the implementors of a compiler/load/runtime
environment to make sure that arguments expected in registers are
passed in registers.
