Yes, it's definitely a good idea.
How often will the min and max arguments be chosen to be different from
the minimum and maximum of the type? I'd like to see variants which take
the type as argument and deduce the min and max via TYPE_MINIMUM and
TYPE_MAXIMUM from intprops.h.
ADD_OVERFLOW (a, b, unsigned int)
is easier to write and understand than
ADD_OVERFLOW (a, b, 0, UINT_MAX)
