+       * sysdeps/ieee754/dbl-64/s_sin.c (t22): Consolidate const
+       definition...
+       (slow1, slow2, sloww1, sloww2, bsloww1, bsloww2, cslow2,
+       csloww1, csloww2): ... from here.

        * sysdeps/ieee754/dbl-64/usncs.h: Define constants as double
        instead of structures.
        * sysdeps/ieee754/dbl-64/s_sin.c (POLYNOMIAL2): Adjust.
