+- `-Wpragma-pack` is a new warning that warns in the following cases:
+  - When a translation unit is missing terminating `#pragma pack (pop)`
+    directives.
+  - When leaving an included file that changes the current alignment value,
+    i.e. when the alignment before `#include` is different to the alignment
+    after `#include`.
+  - `-Wpragma-pack-suspicious-include` (disabled by default) warns on an
+    `#include` when the included file contains structures or unions affected by
+    a non-default alignment that has been specified using a `#pragma pack`
+    directive prior to the `#include`.
