I think there are two different things here. LUA_USE_APICHECK does not
need lua_assert, as it defines luai_apicheck using assert directly.  As
its name implies, it checks only the API, not Lua internals.  (Usually
this is what people want.) However, if you are hacking the *insides* of
the Lua kernel, then it may be worth defining lua_assert. You can also
consider using ltests.h/ltests.c (distributed with the test files),
which defines lua_assert and some other checks (e.g., a basic allocator
check).
