Update.

2001-09-04  Jakub Jelinek  <jakub@redhat.com>

	* iconv/strtab.c (strtabinit): Initialize null Strent.
	(newstring): Move len == 0 handling...
	(strtabadd): ...here.
	If len == 1, return null Strent.
	When inserting a suffix of an existing string, check if
	it is not equal to some suffix already recorded.
	Copy left and right members over if adding longer string.

2001-09-04  Jakub Jelinek  <jakub@redhat.com>

	* sunrpc/rpc_cout.c (upcase): Account for trailing '\0'.

	* sysdeps/unix/sysv/linux/alpha/gethostname.c: Include <errno.h>.
	(__syscall_gethostname): Add prototype.
