I found that confusing too.  But the difference is that in the
assembly implementation, the prototype declaration doesn't matter, as
it is the assembly code that determines the symbol name in the
function definition, whereas in C it is the prototype declaration that
has the symbol renamed.

As soon as I get confirmation on whether we're to actually hide
_exit() or not.
