The §376 class's real blocker: after fix_arity_callers no-protos the conflicting
forward decl, the draft's definition becomes the prototype in scope and the TU's
own call site fails with 'too few arguments'. Casting THAT call site to a 0-arg
function pointer is byte-neutral (gcc-2.7.2 folds a cast of a known symbol back
to a direct jal, §20) and banks the function.
