C++ :: Standard Template Library (uppercase And Lowercase)

so the Standard Template Library isn't portableANSI? I'm studing C++ using the Teach Your Self C++ in 1 Hour a Day. but seems these code isn't correct for GNU compiler:

Code:
#include <string>
#include <iostream>
#include <algorithm>
int main () {
using namespace std;
cout << "Please enter a string for case-convertion:" << endl;

[Code] ....

i get several errors:
"C:UsersJoaquimDocumentsCodeBlocks estmain.cpp|16|error: no matching function for call to 'transform(std::basic_string<char>::iterator, std::basic_string<char>::iterator, std::basic_string<char>::iterator, <unresolved overloaded function type>)'|"
