(C++) Compile warning

Warning emitted by the compiler, but does not prevent program execution. A compile error does prevent program execution.

Compile cleanly at high warning levels [1]. Prefer compile errors to runtime errors [2].

• 'auto' will change meaning in C++0x; please remove it
• Cannot create pre-compiled header: initialized data in header
• left shift count >= width of type
• lexical_cast.hpp: Negating unsigned value
• Object::connect: No such slot QDialog::my_slot()
• type qualifiers ignored on function return type
• unused parameter 'seq'
