/* Reason for rewrite:
* Even though in the current verification setup, `FreeRTOS.h` is always
* included before this file is processed, VeriFast does not consider this
* context when processing this file. VeriFast forbids macro expansions to
* depend on a potentially variable context, e.g, `configSTACK_DEPTH_TYPE`
* which expands to 'uint16_t' if and only if `FreeRTOS.h` has been
* included.
