"The Free Software community is well known for its diversity. This is most obvious at the application level, but even exists in the context of operating systems. David Chisnall takes a break from UNIX-derivatives and explores some of the more esoteric options." Note: From experience, I can say that the author's claim that "Haiku is more or less ready for their 1.0 release in terms of features" is a bit overambitious.

The ABI was changed to comply with the cross-vendor C++ ABI. It wasn't like the GCC guys sat down one day and said "Hey you know what, let's change the C++ ABI for the hell of it. That'll really annoy everyone!"
Well technically GCC 3.X and later use the name mangling scheme dictated by the IA64 ABI. It's hardly a standard on other processor architectures (though from what I gather, Intel's C++ compiler uses it for x86 as well, but this is unsurprising since Intel is responsible for the IA64 ABI).
See http://en.wikipedia.org/wiki/Name_mangling#How_different_compilers_...
You would think they would have left an option for the old way, but perhaps they made other ABI changes (like the way exceptions are handled) that would have made having a proper backwards compatability option practical.

Well, the IA64 ABI is the Cross Vendor ABI. See http://gcc.gnu.org/onlinedocs/libstdc++/libstdc++-html-USERS-3.3/na...
"GCC subscribes to a relatively-new cross-vendor ABI for C++, sometimes called the IA64 ABI because it happens to be the native ABI for that platform."
