Ok Thanks for setting me straight. 

Now Ive got a similar problem with replace() and I don't know if this is
the same situation. How do I tell if my function is not supported ? I'd
like to be able to know, because if it is supported, the error is
probably mine.  
This is based on the example on page 1173 pf c++ Primer by Lippman and
Lajoie, a reliable text. 

#include <string>
#include <algorithm>

int main()
{
    string str = "The rain in Spain falls mainly on the plain\n";
    cout << "string:"<< str;
    string oldval = "rain";
    string newval = "sleet";
    replace (str.begin(), str.end(), oldval, newval) ;
    cout << "new str:"<< str;
}

I get these messages:
c:/djgpp/lang/cxx/stl_algo.h: In function `void replace<char *,
string>(char *, char *, const string &, const string &)':
replace.cpp:11:   instantiated from here
c:/djgpp/lang/cxx/stl_algo.h:471: no match for `char & == const
