With both patches applied (on top of trunk from yesterday) on both Linux and
Darwin I am seeing regressions in the C++ and libstdc++ test suites. For the
darwin case, I could perhaps have another merge error - but the Linux case has
only your two patches and configured with
--enable-symvers=gnu-versioned-namespace (only).

many of the libstdc++ fails are of this form:
/home/iains/gcc-master/bld-patched/x86_64-pc-linux-gnu/32/libstdc++-v3/include/format:3519:
error: 'std::__format::_Arg_store<_Context, _Args>::_Arg_store(_Tp& ...) [with

many of the c++ fails are of this form:
contracts-tmpl-spec1.C:(.text+0x6f): undefined reference to
`handle_contract_violation(std::experimental::contract_violation const&)'
