   This may depend on your compiler, and th features of the architecture
   it's compiling for.

   But the solution, for the system which the 300,000 lines of code was
   originally written for, was to use the much faster (at lest on that
   system) assigned GOTOs.

   And "fixing" it is your tax dollars at work.
