macOS What is wrong with my code?

#include <iostream>
using namespace std;

void func1();
void func2();

int count; // this is a global variable

int main()
{
int i; // this is a local variable

for(i=0; i<10; i++) {
count = i * 2;
func1();
}

return 0;
}

void func1()
{
cout << "count: " << count; // access global count
cout << '\n'; // output a newline
func2();
}

void func2()
{
int count; // this is a local variable

for(count=0; count<3; count++) cout << '.';
}

It's something to do with count being used already in the std namespace. If you replace all instances of count with count1 then g++ can compile it fine and it runs as expected.

Edit: note that using the same name for a local and global variable is fine. This looks like code designed to show what happens when you do that and how the scope rules work.
