+	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.
