2.1.2.2 Hosted environment
A hosted environment need not be provided, but shall conform to the

"Program startup"
The function called at program startup is named main . The
implementation declares no prototype for this function. It can be

int main(int argc, char *argv[]) { /*...*/ }
If they are defined, the parameters to the main function shall obey
the following constraints:
