Subject: Re:  should not warning with dead code

A workaround is to use ? : and statement expressions instead of "if".  
This way, the front-end setting of skip_evaluation disables these 
warnings.  (skip_evaluation can't be set for if (0) because you can jump 
into if (0), whereas jumps into statement expressions are not permitted.  
Thus in general you need to parse the whole function body to tell if the 
if (0) is dead.)
