maybe he is reluctant to add it since it would not be a constant
from the Lua side ?

just add and export a C function along this lines to your package:

static int get_bufsiz ( lua_State * const L )
{
  lua_pushinteger ( L,
    // without checking the macro's value :-/
#if defined (BUFSIZ)
    BUFSIZ
#else
    0 // maybe no good idea ?
#endif
    ) ;

  return 1 ;
}
