Update.

2003-01-16  Steven Munroe  <sjmunroe@us.ibm.com>

	* sysdeps/unix/sysv/linux/powerpc/powerpc64/getcontext.S: New file.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S: New file.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S: New file.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S: New file.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/ucontext_i.h: New file.
	* sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h: New file.
	* sysdeps/unix/sysv/linux/configure.in: Minimum kernel for PPC64
	is 2.4.21.

2003-01-16  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/generic/glob.c (glob): Assume sysconf() always returns
	values != -1 for _LIBC.  Use extend_alloca to reallocate alloca'ed
	buffers.

	* sysdeps/generic/sysconf.c: Unconditionally implement
	_SC_GETPW_R_SIZE_MAX and _SC_GETGR_R_SIZE_MAX.
	* sysdeps/posix/sysconf.c: Likewise.
