	* stdio-common/_itoa.h: Don't expand _itoa inline for libc.
	* stdio-common/_itoa.c: Add _itoa implementation.

	* nscd/nscd_gethst_r.c (__nscd_open_socket): Change implementation
	to also send request.  Add parameter to allow this.
	Change callers.
	* nscd/nscd_getgr_r.c: Change __nscd_open_socket caller.
	* nscd/nscd_getpw_r.c: Likewise.
	* nscd/nscd-client.h: Change __nscd_open_socket prototype.
