Solution in C# (judge verdict: Accepted)

using System;

class ITP1
{
    static void Main()
    {
        string str = Console.ReadLine().ToLower();
        int cnt = 0;
        while (true)
        {
            string[] str2 = Console.ReadLine().Split(' ');
            if (str2[0] == "END_OF_TEXT") { break; }
            for (int i = 0; i < str2.Length; i++)
            {
                str2[i]=str2[i].ToLower();
                if (str2[i] == str){
                            cnt++;
                        }
            }
        }
        Console.WriteLine(cnt);
