Our diagnostics relating to static assertions were a bit confused. For instance, when in MS compatibility mode in C (where we accept static_assert even without including <assert.h>), we would fail to warn the user that they were using the wrong spelling (even in pedantic mode), we were missing a compatibility warning about using _Static_assert in earlier standards modes, diagnostics for the optional message were not reflected in C as they were in C++, etc.
