There is a long distance traveled here between fine tuning warnings and medically critical software. The fact is that building such medically critical software (which I have done) has many more considerations than warning levels of c compilers. Additionally, there is the C language and what the standard says are two different things. Finally, the vast area of standard specified undefined and implementation defined areas substantially impact writing correct software.
