Annex A of the ISO/IEC 14882-2003 C++ Standard lists compiler behaviors that are beyond the scope of the standard, but which must be documented for a compiler implementation. This annex also lists minimum guidelines for these behaviors, although a conforming compiler is not required to meet these minimums.
The CodeWarrior C++ compiler has these implementation quantities listed in the following table, based on the ISO/IEC 14882-2003 C++ Standard, Annex A.
