+       Remove case insensitive option matching.
+       * argmatch.h (argcasematch): Remove declaration.
+       (ARGCASEMATCH): Remove macro.
+       (__xargmatch_internal): Remove case_sensitive argument.
+       (XARGMATCH): Update.
+       (XARGCASEMATCH): Remove macro.
+       * argmatch.c (argmatch): Renamed from __argmatch_internal. Remove
+       case_sensitive argument.
+       (argcasematch): Remove function.
+       (__xargmatch_internal): Remove case_sensitive argument.
+       (main): Use XARGMATCH instead of XARGCASEMATCH.
+
        * xmalloc.c: Change compile-time error message. Add comment about
        required autoconf version.
