+
+ While old code can continue to refer to these macros, new code is

+ and ``strcmp() != 0''.
+
+ This is because modern compilers can directly inline strcmp()
+ 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. */
