MSYS2/MINGW64, for having adopted GCC-5.2, had to recompile *all* its
packages, and a few didn't rebuilt any more and are out of distribution..
On OSX and friends, things are no better..
No, that's certainly not true. Some people may *choose* to recompile with
newer compilers because they want to. That doesn't mean that the older
compiled code was wrong.
We are careful here because we don't want to release compilers that
produce incorrect binaries.
