Well, it's in docs/readme.txt.

That is because you missed the "-D LUA_BUILD_AS_DLL" option which
is needed for building lua.dll and has the effect that the ymbols
declared as "LUA_API" are exported which is how it should be.

The "-rdynamic" option simply tells TCC to export just all symbols,
which then works too, of course.

See this section in luaconf.h (Note however that __declspec(dllimport)
has no effect with TCC. It is not needed for functions, only for
data which TCC doesn't support currently)

/*
@@ LUA_API is a mark for all core API functions.
@@ LUALIB_API is a mark for all standard library functions.
** CHANGE them if you need to define those functions in some special way.

** LUA_BUILD_AS_DLL to get it).
*/
#if defined(LUA_BUILD_AS_DLL)

#if defined(LUA_CORE) || defined(LUA_LIB)
#define LUA_API __declspec(dllexport)
#else
#define LUA_API __declspec(dllimport)
#endif

#else

#define LUA_API         extern

#endif
