Compiling what files?  I don't see any such warnings.  Are you using
unusual options?  What compiler?

It's a GCC bug.  The attributes should be preserved by using typeof in
libc_hidden_proto, but are not.  I see Ulrich has put it in a workaround,
but I think we should have just ignored it and get GCC fixed.
