                     25: \ superfluous stores are removed. GCC removes the superfluous loads by itself

                     31: \    The store is not superfluous although the earlier opt. would think so
                     32: \    Alternatively:    sp[0]=TOS; w=TOS; sp-=1; TOS=w;
                     33: \ 2) ( -- .. ): sp[0] = TOS; ... /* This additional store is necessary */
                     34: \ 3) ( .. -- ): ... TOS = sp[0]; /* as well as this load */
                     35: \ 4) ( -- ): /* but here they are unnecessary */
                     36: \ 5) Words that call NEXT themselves have to be done very carefully.
