C++ does not support long long: QCAD

[H S Rai <hsrai@gndec.ac.in>]

I was trying to compile QCAD, but got following error that 
ISO C++ does not support `long long`. What will be way to 
compile it on Debian system?

-------------------------------
In file included from /usr/include/qt3/qobjectdefs.h:42,
                 from /usr/include/qt3/qobject.h:42,
                 from actions/rs_actioninterface.h:31,
                 from actions/rs_actioninterface.cpp:28:
