Issue description

Clang complains about the use of deprecated builtins and suggests replacements.

This seems to be related to different behavior between Clang and GCC for the "deprecated" builtins. See https://stackoverflow.com/questions/12754886/has-trivial-copy-behaves-differently-in-clang-and-gcc-whos-right

Steps to reproduce

Build the master branch with Clang as compiler.
