When you use gcc to create an executeable, it assumes that you want to
link to the C library.  When you use g++, it assumes you want to link
to the C++ standard library.  That's why you got all the undefined
references to cout and the ostream methods.

Try "gcc -v" and "g++ -v", to see the differences in the processes
invoked by gcc versus g++.
