Code checker doesn't seem to be aware of #define macro's
see the following code from warehouse.cc (around line 288)

#define SET_WORKER_WITHOUT_COST_SPAWNS(nr, value) \
   for \
      (wl_index_range<uint32_t *> \
       i( \ <- this line gives an error about trailing whitespaces
          m_next_worker_without_cost_spawn, \
          m_next_worker_without_cost_spawn + nr \
  ); \
       i; \
       ++i) \
      *i.current = value; \
