           Summary: ImportC: typeof in initializer expression at function
                    scope errors with "circular `typeof` definition"

This valid C code:

int x = sizeof(typeof(x));
int main(){
    int y = sizeof(typeof(y));
}

Errors with:

t.c(3): Error: circular `typeof` definition.

As you can see it does not error at file scope however.
