+
+ * include/features.h (__STDC_ISO_10646__): Set to correct date.
+ Patch by Markus Kuhn <Markus.Kuhn@cl.cam.ac.uk>.
+
+2000-10-06 Jes Sorensen <jes@linuxcare.com>
+
+ * sysdeps/ia64/fpu/fraiseexcpt.c (feraiseexcept): Implement
+ overflow generation by adding DBL_MAX to DBL_MAX instead of
+ setting the bits manually in the fpsr and generating the exception
+ with kill() if necessary.
+ (feraiseexcept): Implement underflow by dividing DBL_MIN by
+ DBL_MIN - similar to the overflow change described above.
+
+2000-08-27 H.J. Lu <hjl@gnu.org>
+
+ * sysdeps/unix/sysv/linux/ia64/clone.S: Make it a dummy as clone
+ is not supported under Linux/ia64, use clone2.
+
+2000-10-06 Jakub Jelinek <jakub@redhat.com>
+
+ * malloc/malloc.h (__THROW): Define to nothing if not gcc.
+ * misc/sys/cdefs.h (__THROW): Likewise.
