### Miscellaneous
##### `UNITY_EXCLUDE_STDDEF_H`
Unity uses the `NULL` macro, which defines the value of a null pointer constant,
defined in `stddef.h` by default. If you want to provide
your own macro for this, you should exclude the `stddef.h` header file by adding this
define to your configuration.
_Example:_
#define UNITY_EXCLUDE_STDDEF_H
