Well, I won't argue here, but still I believe the error reported by GCC 
7.1.0 is something that should be fixed into the sources no matter of the 
compiler used (apparently some ignore it while others report it). I tried 
clang for building V8, but I had much more errors (than with GCC), which 
would perhaps be a subject for another thread when I'm unable to fix the 
GCC build myself (or with some help from the community).

Why it is there in first place then? Shouldn't it be removed upstream, so I 
do not have to manage my own patches for this?

Yes, OK, I though it's clear enough that I cloned the repository, so using 
the most recent version (i.e. or several days old). However, you're right 
it's sometimes important to know the last hash, because changes are 
committed constantly. Nevertheless I do not think this information would 
have been of a match use, because what you wrote there doesn't give me much 
optimism that the problem would be fixed upstream (e.g. it doesn't matter 
much whether I use version 1, 2 or more days old).

Even when eventually it would be shared between several applications? 
Hmm... I'll check what exactly the dependent application requires.
