+       * sysdeps/unix/sysv/linux/x86_64/bits/sigcontext.h: Don't
+       include <bits/wordsize.h>.  Check __x86_64__ instead of
+       __WORDSIZE.
+       (sigcontext): Use "__uint64_t" instead of "unsigned long int"
+       if __x86_64__ is defined.  Use anonymous union on fpstate.
+
        * sysdeps/unix/sysv/linux/x86_64/sys/user.h (user): Use
        anonymous union.
