+	Use GNULIB_POSIXCHECK instead of GNULIB_PORTCHECK.
+	* lib/time.in.h (asctime, asctime_r, ctime, ctime_r): Test
+	GNULIB_POSIXCHECK, not GNULIB_PORTCHECK. Provide compile-time warnings
+	rather than link errors.
+
 2010-03-27  Bruno Haible  <bruno@clisp.org>
 
 	Avoid side effects from tests-related modules on the compilation of lib.
