Solution in C# (judge verdict: Accepted)

using System;
class ITP1_9_A
{
    static void Main()
    {
        int counter = 0;
        string target = Console.ReadLine();
        while (true)
        {
            string[] rl = Console.ReadLine().Split(' ');
            if (rl[0] == "END_OF_TEXT") break;
            for (int i = 0; i < rl.Length; i++)
                if (string.Equals(target, rl[i], StringComparison.OrdinalIgnoreCase)) counter++;
        }
        Console.WriteLine(counter);
    }
