Sat Jan 18 22:15:26 1997  Richard Henderson  <rth@tamu.edu>

	* config.make.in (install_root): New variable to make it easy to
	install glibc somewhere other than /.

	* shlib-versions: alpha-*-linux-* libc=6.1.

	Since sigset_t no longer fits in a register, we can't pass in the
	thread's initial mask so easily.  Take this opportunity to simplify
	the clone implementation by only accepting a single void* argument.

	* sysdeps/unix/sysv/linux/sparc/clone.S: Likewise.
	* sysdeps/unix/sysv/linux/schedbits.h: Update clone prototypes.

	* sysdeps/unix/sysv/linux/alpha/ioctl-types.h: Remove.
	Default Linux version should be sufficient.

	* sysdeps/unix/sysv/linux/alpha/sigprocmask.c: The osf_sigprocmask
	system call wants the sigset dereferenced.

	* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add entries for
	__syscall_ustat and __syscall_xmknod.
	* sysdeps/unix/sysv/linux/alpha/xmknod.c: Include sys/sysmacros.h.

	* sysdeps/unix/sysv/linux/sigset.h: Use longs instead of ints.

	* sysdeps/unix/sysv/linux/tcsetattr.c: Fix pointer dereferences.

	* sysdeps/unix/sysv/linux/alpha/sigsuspend.c: Add comment about
	dependency to kernel type.

	* sysdeps/unix/sysv/linux/alpha/termbits.h: Correct comment.
