What? Microsoft implemented C99 and can now compile the Linux Kernel? Nope. Nothing to see here; move along. Maybe in another 15 years? Yes compiling the version of C from 1999 is too much work for the largest software company on earth.
EDIT: Actually the largest software company was Microsft back in 1999, but now it's Apple and they did write a C99 compiler that can compile the Linux Kernel. Coincidence?
did you actually read what this is about? It's about debugging, not about compiling.
You just seem to have taken this as an opportunity for some ranting which doesn't even make that much sense. Did you think about the fact that even if MS would have a C99 compiler, it extremely likely would still not be able to compile the kernel because of the tons of platform- (and even compiler- if I remember correctly) specific stuff in there.
Also Apple the largest software company? Not Google or so? Numbers? Evidence?
