+       * misc/sys/select.h (__FD_MASK): Renamed from __FDMASK.
+       (__FD_ELT): Renamed from __FDELT.
+       * misc/bits/select2.h (__FD_ELT): Likewise.
+       * bits/select.h (__FD_SET, __FD_CLR, __FD_ISSET): Use __FD_ELT,
+       __FD_MASK instead of __FDELT, __FDMASK.
+       * sysdeps/i386/bits/select.h (__FD_SET, __FD_CLR, __FD_ISSET):
