NOTE: cagney/2000-03-14:

123 |

124 |
|
|
While old code can continue to refer to these macros, new code is
|
125 |
|
|
probably better off using strcmp() directly vis: ``strcmp() == 0''
|
126 |
|
|
and ``strcmp() != 0''.
|
127 |
|
|
|
128 |
|
|
This is because modern compilers can directly inline strcmp()
|
129 |
|
|
making the original justification for these macros - avoid function
|
130 |
|
|
call overhead by pre-testing the first characters
|
131 |
|
|
(``*X==*Y?...:0'') - redundant.
|
132 |
|
|
|
133 |
|
|
``Even if [...] testing the first character does have a modest
|
134 |
|
|
performance improvement, I'd rather that whenever a performance
|
135 |
|
|
issue is found that we spend the effort on algorithmic

136 |

optimizations than micro-optimizing.'' J.T. */
