That actually makes no problem on any architecture afaik. The parameter
will be placed in a register or on stack and never accessed. The GC
might move the value around making the register/stack value invalid, but
you never access it anyway.
I don't think there is anything that will verify that the external
declaration and C side have the same number of arguments.
