Warning about -Wmain for local variables

[Prathamesh Kulkarni <prathamesh.kulkarni@xxxxxxxxxx>]

gcc with -Wmain warns for local variables named main.

int foo()
{
  int main = 0;
  return main;
}

a.c: In function ‘foo’:
a.c:3:7: warning: ‘main’ is usually a function [-Wmain]
   int main = 1;
       ^~~~

Is this intended ? I assumed that the warning's intent was for
diagnosing variable named main having only external linkage.

Thanks,
Prathamesh
