Don't forget the GNU/Linux and gcc are joined at the hip.  Anywhere gcc 
can go, GNU/Linux in some form can follow.

But the GNU/Linux kernel only builds with gcc, or with a compiler 
specifically tailored to build it such as the Intel compiler.  So in 
this specific context, the ABI incompatibility argument doesn't really 
hold water.

 From what I've heard and read over the years, the objections to C++ 
from GNU/Linux kernel developers are more philosophical dressed up as 
practical than practical.
