Consider the following enumeration declaration:
  enum status { ok = 0, err = -1, foo, bar };
The enumerators 'ok' and 'foo' will have the same value.  This may be what the programmer intended, 
but it's more likely to be an oversight.  The C and C++ front ends should have a warning (which 
probably should not be enabled by default or with -Wall) for enumerations whose enumerators have 
duplicate values, since duplicates are likely to be a sign of programmer error.
