	* libc-symbols.h (link_warning): Take new first arg SYMBOL; ask
	for a warning on references to that specific symbol, not the
	entire containing object file.
	(stub_warning): Pass symbol name to link_warning.
	* stdio/gets.c: Pass function name in link_warning invocation.

	* hurd/intr-msg.c: Treat apparent EINTR return from msg trap like
	MACH_SEND_INTERRUPTED.  That indicates interrupt_operation was
	sent, but failed.

	* stdlib/msort.c: Include memcopy.h.
	(msort_with_tmp): If operating on aligned op_t words, use direct word
	fetches and stores.

	* sysdeps/i386/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC): Add
	missing backslash.
