you could also use
lua_Unsigned umax = ~ 0 ;
to determine this upper maximum.
this has the advantage that you do not need to know what C integer type
is actually used as Lua integer type.
Doesn't that need to be:
lua_Unsigned umax = ~(lua_Unsigned)0;
to cover all of the cases that the C standard supports? It's been a while since I've had my head that deep in this, but I know that 0 is of type signed int. What I don't remember is if sign extension applies BEFORE or AFTER converting to unsigned; that _expression_ might end up being 0x00000000FFFFFFFF if it converts to unsigned before doing sign extension.
