>Description:
When calling cin.rdbuf()->in_avail() without any input in the buffer, in_avail() blocks until input is ready, and then returns 1, instead of the number of characters read. This is not adhering to the ISO standard. gcc 2.95.x didn't do that. It correctly returns 0 when nothing is available etc.
>How-To-Repeat:
#include <iostream>

using namespace std;

int main()
{       // This call blocks, which it shouldn't.
        cout << cin.rdbuf()->in_avail() << endl;
}
