/* Macros to do string compares.
NOTE: cagney/2000-03-14:
While old code can continue to refer to these macros, new code is
probably better off using strcmp() directly vis: ``strcmp() == 0''
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. */
