[SDK] Add GCC overrides for SAL annotations GCC has some functions, variables & type attributes which can be used as aliases for some of the SAL annotations. Although it's not as rich & precise, it's still useful since we actually enable -Werror on GCC builds whereas we don't use such an option on MSVC builds. For now, _Must_inspect_result_ is aliased to warn_result_unused attribute. 2021-06-17 12:48:52 +00:00			`/*`
