From src/umain.c:

int main(int argc, char *argv[])
{
   int (*real_main) (int, char*[]) = (int (*) (int, char*[])) 
_mangled_main_address;

   __crt0_argc = argc;
   __crt0_argv = argv;

   return (*real_main)(argc, argv);
}

Using the function pointer allows the real main() routine to be either 
main(void) or main(int, char**). Always using a function pointer would 
eliminate the need to have the user declare his main as  main(int, 
char**).
But that may be what you were saying anyway.
