   Both the hardware, and myself, care about the code that   
   C compilers generate.   
      
   I'm happy to modify a C compiler if necessary. Or pay   
   someone else to do it, as I have been doing already.   
      
   That is my interest, and that is my question.   
      
   I don't care if Fortran or Turtle Graphics or some other   
   language has a perfectly valid reason for hardcoding   
   the number 4.   
      
   I care about C90, where I am willing to, and have,   
   inspected the assembler output of DOS C compilers.
