/**
@defgroup   sys_cpp_new_delete  C++ new and delete operator module
@ingroup    sys
@brief      This module provides the `new` and `delete` operators for platforms
            that do not use `libstdc++`.
@warning    This module is automatically selected, if needed. Never add it
            manually.

# Background

On some platforms `libstdc++` is not used or not available, like on the AVR.
Such platforms can use this module to implement the C++ `new` and `delete`
operators using `malloc` and `free` respectively. However, to be thread-safe,
a thread-safe implementation of `malloc` and `free` must be present.

# Usage

This module is intended to be use by platforms that not providing the required
operators. Hence, application developers and users should never select this
module by hand.
