Yes, at least check is function-like:

  #define check(assertion)                                                   \
      do                                                                      \
      {                                                                       \
          if ( __builtin_expect(!(assertion), 0) )                            \
          {                                                                   \
              DEBUG_ASSERT_MESSAGE(                                           \
                  DEBUG_ASSERT_COMPONENT_NAME_STRING,                         \
                  #assertion,                                                 \
                  0,                                                          \
                  0,                                                          \
                  __FILE__,                                                   \
                  __LINE__,                                                   \
                  0);                                                         \
          }                                                                   \
      } while ( 0 )
