Hum. I don't know what the two of you are going on about. :-)

As far as I know, you can still compile a program that don't have 
function prototypes in current C, and you can definitely do it in C89.

So K&R style code is still compilable. Obviously, "modern" C won't pass 
the K&R compiler, but that's more expected.

But there might be something in old K&R code that is not acceptable in 
newer compilers. I can't think of anything now, but that might just be me.

But array bounds checking is never going to be possible in C, since 
arrays are mostly syntactic sugar to start with.
