These five compilers were GCC (mingw32), g++ (MINGW32), GCC (Linux i386), g++ (Linux i386), and Microsoft Visual C + + 6.0. Unfortunately, there is no combination of definitions and outputs that are compatible with these five compilers . To get a thorough understanding of the different compilers for 64-bit integers, I wrote the program to evaluate them, as shown in the table above.
