I have followed your other suggestions, but this one doesn't work, since
ML_arg is defined in included C code, not via an export pragma, and thus
isn't declared in std_util.h.

It is arguable that such C functions belong in the runtime, but there is
no point in addressing this outside the context of the reorganization of
the part of the library dealing with RTTI.
