If it's a non-problem for C++, why does Autoconf upgrade to C++11 when 
the default is C++98? Autoconf has done so since Autoconf 2.70 (2020), 
with nobody complaining as far as I know.

Was the Autoconf 2.70 change done so late that it had no practical 
effect, because no distro was defaulting to C++98 any more? If so, it 
sounds like Autoconf should go back to its 2.69 behavior and not mess 
with the C++ version as that's more likely to hurt than help.

For background on that Autoconf 2.70 change, see this 2013 thread:
