redhat linux 7.2 dual pentium 800Mhz
>Description:
#include <map>
#include <fstream>
#include <iostream>

#include <string>
#include <algorithm>
using namespace std;
typedef map<string,int> Index;
int main(int argc, char* argv[]) {
    Index index;
    ifstream ifs(argv[1]);
    string word;
    while(ifs >> word) {
        transform(word.begin(),word.end(),word.begin(),tolower);
        index[word]++;
    }
    cout.setf(ios::left);
    for(Index::const_iterator i = index.begin(); i != index.end(); ++i) {
        cout << setw(20) << i->first << " : " << i -> second << endl;
    }
    return 0;
}

transform function won't accept to lower without a typecast.
for_each function will not work either for the same reason.
