Incompatible pointer type

Why does gcc bitch about incompatible pointer types?
A variable int number;
A function func(int *number);
And a function call like this func(&number);

Compiles fine, and works fine. But when I change the type, for example to uint16_t number; func(uint16_t *number); gcc throws a warning about incompatible pointer type.

Does gcc hate me?

It's just you:

#include <iostream>
#include <stdint.h>

using namespace std;

void foo(uint16_t* pf)
{
  cout << *pf << endl;
}

int main() {
  uint16_t foobar = 42;
  foo(&foobar);
}
