First, exactly that was the question: Does this only affect building
with MSVC?

Obviously nonsense arguments like this are really counter-productive
1) even today it is still quite possible to just not connect a computer to the
internet, and FFmpeg still works fine without one
2) are there even any botnet programs around that will still run on Windows 98?

Generally I think we can handle it the usual way for fringe platforms:
If someone is willing to maintain it and it does not make the code too
messy that is welcome.
Though I have to say that the *snprintf return value is the typical kind
of thing that I think is quite likely to have bugs because it is rather
complex to implement and thus I'd in principle prefer to not rely on it
if reasonably avoidable...
