   22: \ This is not very nice (hard limits, no checking, assumes 1 chars = 1)
   23: 
   24: \ Optimizations:
   25: \ superfluous stores are removed. GCC removes the superfluous loads by itself
   26: \ TOS and FTOS can be kept in register( variable)s.
   27: \ 
   28: \ Problems:
   29: \ The TOS optimization is somewhat hairy. The problems by example:
   30: \ 1) dup ( w -- w w ): w=TOS; sp-=1; sp[1]=w; TOS=w;
   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.
   37: \
   38: \ To do:
   39: \ add the store optimization for doubles
   40: \ regarding problem 1 above: It would be better (for over) to implement
   41: \ 	the alternative
