(j3.2006) C1x standard

[Keith Bierman]

The compiler writer(s) may support a bevy of platforms. They may even have to cope with multiple C compilers on several of the platforms 

I agree that it would be a great kindness to users if there was less underlying complexity and layers

But the current industry trend is to encapsulate an entire stack in a VM rather than "just" solve minor issues between C programs (or C C++ perl and java version skew)
