+       fseeko: Fix C++ test error on mingw.
+       * m4/fseeko.m4 (gl_HAVE_FSEEKO): New macro, extracted from
+       gl_FUNC_FSEEKO.
+       (gl_REPLACE_FSEEKO): Also set REPLACE_FSEEKO if appropriate.
+       (gl_FUNC_FSEEKO): Require gl_HAVE_FSEEKO. Update.
+       * m4/fflush.m4 (gl_REPLACE_FFLUSH): Don't fiddle with internals of the
+       fseeko module. Instead, invoke gl_REPLACE_FSEEKO.
+
+2010-04-05  Bruno Haible  <bruno@clisp.org>
+
        duplocale: Improve test output.
        * tests/test-duplocale.c (main): Print reason for skipped test.
