128 | NOTE: cagney/2000-03-14: | |
129 | ||
130 | While old code can continue to refer to these macros, new code is | |
131 | probably better off using strcmp() directly vis: ``strcmp() == 0'' | |
132 | and ``strcmp() != 0''. | |

136 | call overhead by pre-testing the first characters | |
137 | (``*X==*Y?...:0'') - redundant. | |
