Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

class Program {
    private static int Main() {
        var W = Console.ReadLine();
        W = W.ToLower();

        int count = 0;

        bool isEnd = false;
        while( !isEnd ) {
            var input = Console.ReadLine();
            isEnd = input.EndsWith( "END_OF_TEXT" );

            input = input.ToLower();

            var values = input.Split( ' ' );
            count += values.Count( _ => _ == W );
        }

        Console.WriteLine( count );

        return 0;
    }
