Update.
1998-10-29 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sigaction.c (__sigaction): Allow compiling on systems without rt_sigaction syscall. 1998-10-12 Philip Blundell <pb@nexus.co.uk> * Makeconfig (sysdep-subdirs): Allow Subdirs files to remove directories as well as add them. 1998-10-28 Philip Blundell <pb@nexus.co.uk> * sysdeps/unix/sysv/linux/neteconet/ec.h: New file. Support for AF_ECONET sockets as found in recent Linux 2.1 kernels. * sysdeps/unix/sysv/linux/Dist: Distribute it. * sysdeps/unix/sysv/linux/Makefile: Install it. 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.
