Flagging non-conformance is not possible in general as there are more creative fools out there than there are compiler writers.

There are zillions of ways to write non-conforming code, for example an endless loop is not conforming in C++. The compiler is not obliged to diagnose it, but it is allowed for the compiler to silently optimize the non-conforming code away, assuming it is never called. At least that's what g++ folks think.

Syntax errors and many types of constraint violations will be flagged by the parser. But there are endless possibilities of non-conforming behaviour that cannot be seen at compile time.
Does enables conformance mean: Flags syntactic non conformance?
/std:c11
The /std:c11 option enables ISO C11 conformance. It's available starting in Visual Studio 2019 version 16.8.
/std:c17
The /std:c17 option enables ISO C17 conformance. It's available starting in Visual Studio 2019 version 16.8.
