        * Makefile.am.in (Makefile.am): Don't mention jm-glibc-io.m4n
        and jm-glibc-io.m4, as they are no longer a special case.
-       * jm-glibc-io.m4: New file.
-       * jm-glibc-io.m4n: Remove.
+       * jm-glibc-io.m4: Rename from jm-glibc-io.m4n, and remove the
+       kludge and the auto-generation stuff.  Check only whether the
+       functions are declared, not whether they exist, since older hosts
+       that don't declare the functions can't use the optimization anyway.
