+ * math/test-misc.c: Add more tests for nextafter.
+ * sysdeps/i386/fpu/s_nextafterl.c: Handle decrement for x<0 correctly.
+ * sysdeps/ieee754/ldbl-96/math_ldbl.h
+ (ieee_long_double_shape_type): Make sign_exponent element signed.
+
* manual/message.texi: Add Estonian to plural overview list.
Correct rule for Slavic languages.
Patch by Stanislav Brabec <utx@penguin.cz>.
