We're only changing the\ndefault here. Reconfiguring when the default changes isn't always a good\nidea. I suppose what's missing in meson is a way to force a minimum (or\nparticular) C++ standard. Or maybe that feature exists and we're just\nnot aware of it :-) I've asked in #mesonbuild.\n\n> > Patches 2/5 and 3/5 then update the code base to remove workarounds\n> > needed by C++14 and older compilers.
