Modern C compilers are "undermining what C tries to achieve" too. 
GCC has '-fwrapv' option for wrapping signed ints and 
'-ftrivial-auto-var-init=' option for preventing variables from 
being accidentally left uninitialized. There's also 
'-fno-strict-aliasing' option for eliminating the root cause of a 
certain class of hard to debug problems. All of this together 
forms a kind of somewhat safer non-standard C dialect, which is 
still fully compatible with the existing C code.
