No the bug was the same.

Following changes are needed in the code:

a) leading :: before namespace:

   ::boost::algorithm::detail::trim_begin(
should be
   boost::algorithm::detail::trim_begin(

everywhere (BCB doesn't like it).

b) the begin() and end() needs to be fully qualified for BCB:

                boost::algorithm::detail::trim_end(
                    boost::begin(Input), <<== here
                    boost::end(Input), <<== here
                    IsSpace ),

on both places where compiler complains.

c) The iterator needs to be explicitly declared.

I rewrote it into:

        template<typename SequenceT, typename PredicateT>
        inline void trim_right_if(SequenceT& Input, PredicateT IsSpace)
        {
            SequenceT::iterator it = 
boost::algorithm::detail::trim_end(boost::begin(Input), boost::end(Input), 
IsSpace);
            Input.erase(it, boost::end(Input));
        }

and

        template<typename SequenceT, typename PredicateT>
        inline void trim_left_if(SequenceT& Input, PredicateT IsSpace)
        {
            SequenceT::iterator it = 
boost::algorithm::detail::trim_begin(boost::begin(Input), boost::end(Input), 
IsSpace);
            Input.erase(boost::begin(Input), it);

        }

and then it compiles (with your latest CVS version).
