Update.
1998-10-27 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * string/bits/string2.h: __USE_GNU already implies __USE_MISC. 1998-10-27 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * sysdeps/generic/bits/types.h (__FDS_BITS): New macro to access fds_bits member. * sysdeps/unix/sysv/linux/alpha/bits/types.h (__FDS_BITS): Likewise. * sysdeps/unix/sysv/linux/bits/types.h (__FDS_BITS): Likewise. * sysdeps/unix/sysv/linux/mips/bits/types.h (__FDS_BITS): Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/bits/types.h (__FDS_BITS): Likewise. * sysdeps/unix/sysv/sysv4/solaris2/bits/types.h (__FDS_BITS): Likewise. * sysdeps/generic/bits/select.h (__FD_ZERO, __FD_SET, __FD_CLR, __FD_ISSET): Use it. * sysdeps/i386/bits/select.h (__FD_ZERO, __FD_SET, __FD_CLR, __FD_ISSET): Likewise.
