No, the major number changes every time there's an ABI break.  There 
have been three under my maintainership, so we're at ABI v4.

It's unfortunate that the ABI breaks so easily with C++.  With C, 
there's no problem just adding new functions.  But when you add methods 
to a C++ class, it changes the instance size, so it's a different ABI.  Wah.

I'm taking a consequence of this topic up in a new thread.
