It's "/W4".  The default appears to be "/W3".

With "/W4", or even "/Wall", it still doesn't diagnose a stray semicolon
at file scope.  (I wouldn't expect a warning option to be the
incantation that makes the compiler conform to the standard.)

The "/Za" option is supposed to disable language extensions, but it
complains that "'/Za' and '/std:c17' command-line options are
incompatible".

The implementation supports both C and C++.  It seems to treat C as a
second-class citizen.  (I think, but I'm not sure, that a stray
semicolon at file scope is legal in C++; it's called an
"empty-declaration".)

I'd say that Microsoft's compiler loses the syntax battle.
