Disregarding the arguments about this and answering your question, we do 
this in a simpler way than the first solution posted. In our method you 
don't have to add another variable to the entire object structure, rather 
just add a few flags.

In structs.h and constants.c, define your new ITEM flags. We call them 
LVL10, LVL20., LVL30, etc. Then in handler.c you will find a piece of 
code called invalid_class. This is the function that checks to see if a 
character can't use an item because it is not usable by his/her class. At 
the end of these checks, just add your new checks for the equipment like 
below. Granted it uses up some flags, but in exchange, adding a limit is 
as simple as adding another bit to the item in the object file.

int invalid_class(struct char_data *ch, struct obj_data *obj) {
      (IS_OBJ_STAT(obj, ITEM_ANTI_CLERIC) && IS_CLERIC(ch)) ||
      (IS_OBJ_STAT(obj, ITEM_ANTI_THIEF) && IS_THIEF(ch)) ||
      (IS_OBJ_STAT(obj, ITEM_LVL10) && (GET_LEVEL(ch) <= 9)) ||
      (IS_OBJ_STAT(obj, ITEM_LVL20) && (GET_LEVEL(ch) <= 19)) ||
      (IS_OBJ_STAT(obj, ITEM_LVL30) && (GET_LEVEL(ch) <= 29)) ||
      (IS_OBJ_STAT(obj, ITEM_LVL40) && (GET_LEVEL(ch) <= 39)) ||
      (IS_OBJ_STAT(obj, ITEM_LVL50) && (GET_LEVEL(ch) <= 49))) 
	return 1;
 /* else*/
	return 0;

We have 60 mortal levels, so the 5 flags are enough for us. Also, we have 
another way to add more flags if we run out. We do it for PRF_FLAGS by 
adding a new set called PRF2_FLAGS. Works out nicely since we added new 
communication channels and you can now be !MUSIC, !IMMNET, etc. I know 
lots of people were looking for ways to add more flags and this is a 
simple way. It didn't even require a p-file wipe. When you sdsstat a 
player, they now have another field under "PRF" that says "PRF2: None" or 
whatever. I will dig around for all the pieces of code today and post it 
later if you guysd want it.

Hope that helps,
