Change the gcc to g++ if you use STL and C++ programs.

You are using the wrong compiler. GCC is a C Compiler, but you are
trying to compile and link C++ code. GCC does not know how to handle
this. Please use a C++ compiler - i. e. "g++" - instead.

Peter,
you should use g++ as compiler front end when compiling C++ programs
