At least with g++, you really *need* to provide flags to set the
warning level and C++ standard level, if you're at all interested in
getting warnings about broken code. A good starting point:

  g++ -Wall -Wextra -pedantic -Wold-style-cast -std=c++98 -O3

I expect the other two compilers to behave in a similar way.
