About that "warnings as errors"; for me the reason for that behavior is 
that I usually include executing the code to the command line when coding 
(and use up arrow to rerun it, if the compiler didn't accept my code):

$ make && ./myProgram

If the compiler does not stop for warnings, I'd need some sort of build 
log to examine the warnings after execution. But if the compiler returns 
error value (like -1) when meeting warnings, the program was not executed 
and I can easily examine the reasons.

This same happens of course with IDEs, when using "Run" instead of first 
compiling/building the software.

No, it shows all warnings it generates. But IMO it does not generate 
enough warnings.
