* 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.
