- *  #define inline versions of selected performance-critical text access functions
- *          Caution:  do not use auto increment++ or decrement-- expressions
- *                    as parameters to these macros.
- *
- *          For most use, where there is no extreme performance constraint, the
- *          normal, non-inline functions are a better choice.  The resulting code
- *          will be smaller, and, if the need ever arises, easier to debug.
- *
- *          These are implemented as #defines rather than real functions
- *          because there is no fully portable way to do inline functions in plain C.
