Yes, but I think that it is not a common practice in Lua. AFAIK, Lua
has only math.huge [1] to tell what is the biggest number value
available (what isn't the same of having the lua_Number width). Thus,
we would need to provide an interface to return this information. I'd
prefer to have it defined in compile time independently of platform.
Anyway, as I stated before, I have no strong feelings about that.. if
everybody else prefer intmax_t, I have no objection.
