--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
5.1.2.1 General Two execution environments are defined: freestanding and
hosted. In both cases, program startup occurs when a designated C function is
called by the execution environment. All objects with static storage duration
shall be initialized (set to their initial values) before program startup. The
manner and timing of such initialization are otherwise unspecified. Program
termination returns control to the execution environment.
Basically this is correct. Since you are defining a freestanding env, then the
definition of main is outside of the scope of the C standard. Which means it
needs to be matched up correctly.
