Based on your answer and the Boost lambda docs
(http://www.boost.org/doc/libs/1_42_0/doc/html/lambda/le_in_details.html#lambda.bind_expressions) 
I changed the code to:
...
template< typename Predicate >
map<string, string> getObjectsFromMap( const Predicate& aPredicate)
{
        pair< map< string, string >::iterator, bool > (*InsertFn)(const map<string, string>::value_type&) = &map<string, string>::insert;
        map<string, string> matchedObjects;
        for_each(	objectsMap.begin(),
                         objectsMap.end(),
                         if_then(
                                 bind(aPredicate, _1) ,
                                 bind(InsertFn,
                                      &matchedObjects ,
                                      make_pair(bind(&map<string, string>::value_type::first, _1),bind(&map<string, string>::value_type::second,_1)))));
        return matchedObjects;
}

But that gives me more errors than I could imagine. Could you give me a
bit more info as I am really lost here.

TIA
