+* Modified by Philip Hazel for use with Exim. The "replace" and "insert *
+* file" features of the search facility have been removed. Also took out *
+* the declaration of sys_errlist, as it isn't used and causes trouble on *
+* some systems that declare it differently. September 1996. *
+* Added the arguments into the static functions declared at the head, to *
+* stop some compiler warnings. August 1999. *
+* Took out the separate declarations of errno and sys_nerr at the start, *
+* because they too aren't actually used, and the declaration causes trouble *
+* on some systems. December 2002. *
