Sorry. I was just irritated about getting absolutely no answer on
such a simple question.

I didn't realize that LoadError is not a subclass of
StandardError. Now it is obvious to me.

    rb_rescue2( &call_require, (VALUE) name, &rescue_require, Qnil,
                        rb_eLoadError, (VALUE) 0);
