ODR violations are very easy to trigger unless you build the whole thing from source, and are ill-formed, no diagnostic required (worse than UB).

Neither "ODR violations" nor IFNDR exist in C. Incompatibility across translation units can cause undefined behavior in C, but this can easily be avoided.

C simply has less wording for it because less work has been put into it.

The same problems exist.

		The ODR problem is much more benign in C. Undefined behavior at translation time (~ IFNDR) still exists in C but for C2y we have removed most of it already.
