Lizard Skips Odd function Declarations

[MichaelBMiner]

I have a Jenkins pipeline which builds my application then runs various tools. Doxygen, CppCheck, Lizard Code complexity and a few others. In my code many functions are declared as static, this meads my unit tests (ceedling) cannot see them, or test them.

To make them visible for ceedling I have to declare each function as follows

#ifdef CEEDLING_TESTS
uint16_t ring_buffer_advance(uint16_t current_index, uint16_t buffer_size){
#else
static uint16_t ring_buffer_advance(uint16_t current_index, uint16_t buffer_size){
#endif
	if (buffer_size > 0) {
		current_index++;
		if (current_index >= buffer_size) {
			current_index = 0;
		}
	} else {
		printf("error - ring buffer max value can not be zero \n");
		current_index = 0;
	}

	return current_index;
}

Now in the c and h files I use ifdefs to create the appropriate function prototype. Lizard does not find these functions and does not generate a complexity report.
