rt。请大家帮我看一下，这不报错？？？

怎么回事，想知道为啥它不报错

代码：

#include <stdio.h>
#include <114514.h>

signed main() {
#define sss

#ifdef s

int main() {
	#ifdef s
	
	int main() {
		#ifdef s
		
		int main() {
			#ifdef s
			
			int main() {
				#ifdef s
				
				int main() {
					#ifdef s
					
					int main() {
						#ifdef s
						
						int main() {
							#ifdef s
							
							int main() {
								#ifdef s
								
								int main() {
									#ifdef s
									
									int main() {
										#ifdef s
										
										int main() {
											
										}
										
										#endif
									}
									
									#endif
								}
								
								#endif
							}
							
							#endif
						}
						
						#endif
					}
					
					#endif
				}
				
				#endif
			}
			
			#endif
		}
		
		#endif
	}
	
	#endif
}

#endif
}

文件 114514.h 里的类容：

#include <random>
#include <time.h>
