HP will certainly think so.  They have already committed to OS builds
using the new ABI, and they cannot respin libraries, etc.  There are
major parts of the OS written in C++.

Umm, CodeSourcery did those implementations. :-)

Well, it clearly changes the ABI -- programs compiled with and without
the change will not link, in general.

Let's see what other folks say, if anything.
