Update.

2004-10-14  Ulrich Drepper  <drepper@redhat.com>

	* nscd/connections.c (nscd_init): Remove file if not persistent
	and not shared.  Patch by Jerome Borsboom <j.borsboom@erasmusmc.nl>.

	* sysdeps/unix/sysv/linux/i386/setresuid.c: Handle
	defined __NR_setresuid32 && !defined __NR_setresuid.
	* sysdeps/unix/sysv/linux/i386/setresgid.c: Handle
	defined __NR_setresgid32 && !defined __NR_setresgid.

	* sysdeps/sparc/fpu/bits/mathinline.h (__signbitf, __signbit,
	__signbitl, sqrtf, sqrt, sqrtl, fdim, fdimf): Use __NTH macro.

	* sysdeps/generic/errno-loc.c: Don't undef #errno
	if RTLD_PRIVATE_ERRNO.
	* include/errno.h (__errno_location): If RTLD_PRIVATE_ERRNO,
	add attribute_hidden.

	* dlfcn/dlinfo.c (dlinfo_doit): Replace iteration over GL(dl_loaded)
	chain with iteration over all namespaces' _ns_loaded chains.
	* sysdeps/powerpc/powerpc32/dl-machine.c (__elf_preferred_address):
	Likewise.
	* sysdeps/mips/dl-machine.h (elf_machine_runtime_link_map): Likewise.
