* 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.
