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,
