Screen Shot of the Program with trigraphs compiled using Turbo C++

Even in the GCC Compilers, the trigraphs are not getting compiled without explicitly specifying the trigraph attribute.

#include<stdio.h>

int main()
 {
 int a=4;
 if((a==4) ??! (a==5))
   printf("\nHello world!");
 return 0;
 }

This program saved as try.c gets compiled in GCC Compiler only when we specify gcc -Wall -trigraphs try.c and it still shows warnings. Can you enlist some compilers that will treat and handle trigraphs without any errors or warnings?
