Answer 6

Technically compilers do provide some options to define a custom main function. Some engines and API's actually use this feature, for instance C/C++ programs that use the Windows API usually define WinMain as the entry point.

Functionally there's no difference though. Every program needs an entry point (unless it's a library) and that entry function needs to have certain optional arguments depending on platform.
