The gcc compiler will by default compile a .cpp file as C++.   An 
object compiled as C++ will need the C++ runtime to support things like 
exceptions (as seen in your example), global constructors and 
destructors, free store allocation, iostreams, and so forth.

If you want to build a program with C++ objects you need to either use 
the C++ front end 'g++' or if you use the C front end 'gcc' you will 
have to explicitly link in the C++ runtime, '-lstdc++'.
