Update.

2003-01-04  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

	* sysdeps/unix/sysv/linux/powerpc/powerpc32/syscalls.list: Mark
	__syscall_pread64 and __syscall_pwrite64 cancelable.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h
	(INTERNAL_SYSCALL): New macro.
	(LOADARGS_0, LOADARGS_1): Fix.

2003-01-05  Ulrich Drepper  <drepper@redhat.com>

	* Makerules (build-shlip-helper): Unless told otherwise, add
	-Wl,-z,defs to linker command line.
	* rt/Makefile (librt.so): Link with ld.so.
	* dlfcn/Makefile (libdl.so): Likewise.
