As Andreas said, this is an One Definition Rule violation, you need to make the
functions static or put them in an anonymous namespace if you want to have a
different definition in each file.

This compiler is not supported by the GCC project, the oldest supported release
is 4.3

You should report issues with your compiler to Apple.
