-   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. */

-/* NOTE: cagney/2003-11-23: All instances of STREQ[N] covered by
-   testing GDB on a stabs system have been replaced by equivalent
-   str[n]cmp calls.  To avoid the possability of introducing bugs when
-   making untested changes, the remaining references were deprecated
-   rather than replaced.  */
