-   making the original justification for these macros - avoid function
-   call overhead by pre-testing the first characters
-   (``*X==*Y?...:0'') - redundant.
-
-   ``Even if [...] testing the first character does have a modest
-   performance improvement, I'd rather that whenever a performance
-   issue is found that we spend the effort on algorithmic
-   optimizations than micro-optimizing.'' J.T. */

-   making untested changes, the remaining references were deprecated
