If by "caught up", you mean talked about clang-tidy in a separate post, which is definitely not a GCC compiler flag, then sure.
The goalpost, since you're insistent on being explicit about it, was whether a C/C++ compiler "with reasonable flags" will catch the implicit wrap. GCC is a very popular compiler, and to be honest, I'm still not sure how to get it to warn on the above code, if doing so is possible.
Edit: Just read the rest of the thread, it's -Wconversion, which I suppose makes sense. Ignore me, point taken.
