 * The following preprocessor macros allow us to declare

 * they will expand to
 *
 *    extern const char *SERVICE_NAME_S;
 *
 * however if ALLOCATE_SEARCH_TAGS is defined then it will
 * become
 *
 *    const char *SERVICE_NAME_S = "path";
 *
 * ALLOCATE_SEARCH_TAGS must be defined only once prior to
 * including this header file. Currently this happens in
 * search_options.c.
