With suggestion 1, it does get compiled with libstdc++.so.5. It also gets compiled with libstdc++.so.6. See this

Code:
ldd setup | grep libstd
        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x03ff5000)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x007cd000)

I also get a warning.
Code:
/usr/bin/ld: warning: libstdc++.so.6, needed by /usr/lib/qt-3.3/lib/libqt-mt.so, may conflict with libstdc++.so.5

I wonder could this be the reason why libstdc++.so.6 is also required ?

With suggestion 2, I get the error

Code:
/usr/bin/ld: cannot find -lstdc++.5
collect2: ld returned 1 exit status
make: *** [setup] Error 1

Detailed Description
   template<typename _Iterator>class std::reverse_iterator< _Iterator >
       Bidirectional and random access iterators have corresponding reverse iterator adaptors that iterate through the data structure in the
       opposite direction. They have the same signatures as the corresponding iterators. The fundamental relation between a reverse iterator and
       its corresponding iterator i is established by the identity:

       &*(reverse_iterator(i)) == &*(i - 1)

       This mapping is dictated by the fact that while there is always a pointer past the end of an array, there might not be a valid pointer
       before the beginning of an array. [24.4.1]/1,2

       Reverse iterators can be tricky and surprising at first. Their semantics make sense, however, and the trickiness is a side effect of the
       requirement that the iterators must be safe.

Constructor &; Destructor Documentation
   template<typename _Iterator> std::reverse_iterator< _Iterator >::reverse_iterator () [inline]
       The default constructor default-initializes member current. If it is a pointer, that means it is zero-initialized.

       This iterator will move in the opposite direction that x does.
