Please, please, never use #ifdef in code, only in header files.
It's much better to try, e.g,

#ifdef WIDE_CHARACTERS_IN_USE

typedef wchar_t lua_char;
#define lua_fprintf fwprintf
#define lua_atoi    wtoi

...

#else

typedef char lua_char;
#define lua_fprintf fprintf
#define lua_atoi    atoi

...

#endif


And then in the body of the code use

  lua_fprintf(stderr, _T("the cat ate my gymsuit"));
