They might be built-in, but they are still just functions with all their 
limitations:

o Not being able to use them in constant expressions
o Having to use different names depending on the exact type of the argument

So there's nothing to stop someone defined their own min()/max() functions, 
except:

o They would not be standard
o They would need min, umin, lmin, lumin, llmin, llumin, and the same for 
max. (You could probably get away with providing only long long versions, 
but there would be a lot of unnecessary promotions.)

If min(), max() were operators, then that would be it; you wouldn't need 
anything else, not even fmin() and fmax().
