GCC begins move to C++

GCC begins move to C++
[Development] Posted May 31, 2010 13:53 UTC (Mon) by corbet

It's now official: the GCC compiler is moving to a C++ implementation. "I am pleased to report that the GCC Steering Committee and the FSF have approved the use of C++ in GCC itself. Of course, there's no reason for us to use C++ features just because we can. The goal is a better compiler for users, not a C++ code base for its own sake." The next step is the bashing out of a set of C++ coding standards limiting the set of C++ language features which can be used.
