Go backward to g++ for other platforms.
Go up to getting g++.

But I can only find g++-1.42!
=============================

   "I keep hearing people talking about g++ 2.7.2 (or some other number
starting with 2), but the latest version I can find is g++ 1.42.  Where
is it?"

   As of gcc 2.0, C, C++, and Objective-C as well are all combined into
a single distribution called gcc.  If you get gcc you already have g++.
The standard installation procedure for any gcc version 2 compiler will
install the C++ compiler as well.

   One could argue that we shouldn't even refer to "g++-2.x.y" but it's
a convention.  It means "the C++ compiler included with gcc-2.x.y."
