That's not the way GCC (or egcs) has been operating. If someone wants to propose a contribution she is welcome; there is/was no explicit go- ahead from whoever GNU may refer to, though. Most of the new C++ ABI has been implemented by CodeSourcery. > The EGCS 1.1.2 lineage became GCC 2.91 There never was an official GCC release 2.91.
