Hi,
I tried to improve upon my_err function, but I get two warnings:

#define BUFF_SIZE 256
#define my_err(...) \
	do { \
		char buff[BUFF_SIZE]; \
		fprintf(stderr,"\n"); \
		snprintf(buff, sizeof(buff),__FILE__); \
		fprintf(stderr,"FILE:"); \
         	fprintf(stderr,"%s\n" ,buff); \
         	snprintf(buff, sizeof(buff),__FUNCTION__); \
		fprintf(stderr,"FUNCTION:"); \
         	fprintf(stderr,"%s\n" ,buff); \
         	fprintf(stderr,"LINE:%d\n",__LINE__); \
         	snprintf(buff, sizeof(buff),__VA_ARGS__); \
		my_err_s(buff); \
	} while (0)


noreturn void my_err_s(const char * const s)
{
	if ((s == NULL) || (*s == '\0'))
	{
		fprintf(stderr, "Please provide a proper message for "
			 "my_err function.\n");
		exit(EXIT_FAILURE);
	}

	fprintf(stderr,"DATE:%s\n",__DATE__);
	fprintf(stderr,"TIME:%s\n",__TIME__);

	fprintf(stderr, "\nERROR:%s\n", s);
	exit(EXIT_FAILURE);
}

warning: expansion of date or time macro is not reproducible [-Wdate-time]
         fprintf(stderr,"DATE:%s\n",__DATE__);
                                    ^

warning: expansion of date or time macro is not reproducible [-Wdate-time]
         fprintf(stderr,"TIME:%s\n",__TIME__);
                                    ^

What to do to fix the warnings?
