This avoids some warnings when building with -fno-rtti because the function parameters are only used when RTTI is enabled. libstdc++-v3/ChangeLog: * include/bits/shared_ptr_base.h (__shared_ptr::_M_get_deleter): Add unused attribute to parameter. * src/c++11/shared_ptr.cc (_Sp_make_shared_tag::_S_eq): Likewise. Tested powerpc64le-linux.
