It's a small amount of breakage, but it's still a lot more than the _no_=
 breakage that the C committee _used_ to strive for. :-/

We (Autoconf) have had a feature request open for quite some time now fo=
r letting the configure script control exactly which version(s) of each =
language standard are acceptable: https://savannah.gnu.org/support/index=
.php?110286  I do not have time to work on it myself anytime soon but I =
would be delighted to guide anyone who does have the time to work on it.
