[gtkmm] Glib::Unicode::toupper can't be used the same way as toupper

[Morten Brix Pedersen <morten wtf dk>]

Hi,

Using std::string, I converted a string to uppercase doing this:

    std::transform(str.begin(), str.end(), str.begin(), toupper);

I tried the same thing with Glib::ustring and it's toupper function:

    std::transform(str.begin(), str.end(), str.begin(), Glib::Unicode::toupper);

However, gcc 3.1 fails with:

/usr/include/g++-v3-3.1/bits/stl_algo.h: In function `_OutputIter 
   std::transform(_InputIter, _InputIter, _OutputIter, _UnaryOperation) [with 
   _InputIter = Glib::ustring_Iterator<__gnu_cxx::__normal_iterator<char*, 
   std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >, 
   _OutputIter = Glib::ustring_Iterator<__gnu_cxx::__normal_iterator<char*, 
   std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >, 
   _UnaryOperation = gunichar (*)(unsigned int)]':
Utils.cpp:47:   instantiated from here
/usr/include/g++-v3-3.1/bits/stl_algo.h:744: non-lvalue in assignment
