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
