- What is the difference between g++ and gcc? - Stack OverflowGCC or G++ just choose a different front-end with different default options. In a nutshell: if you use g++ the frontend will tell the linker that you may want to link with the C++ standard libraries. The gcc frontend won't do that (also it could link with them if you pass the right command line options).

Options especially prone to this (like loop unrolling) are normally not included in -O3 and are marked accordingly in the manpage.
