exit and system are defined in the C stdlib:
http://en.wikipedia.org/wiki/Stdlib.h

So you need
#include <cstdlib>

FWIW, there aren't many C/C++ users on this mailing list, so general
C/C++ questions like this are generally best asked elsewhere. If you
have questions about C/C++ that are specific to the MonoDevelop IDE,
however, this is the best place :-)
