Well, reading section 3.5.3.3, 'register' is specifically allowed for
function arguments, and all other storage class specifiers are
specifically forbidden.  I presume that this means that it is
significant in matching, probably so the compiler can pass the
argument via a register.  Sign!  Another ambiguity in X3J11.
