When enums are printed with gdb, gdb will show the string which represents
the enum.  If two enums have the same value, the last one defined will
be printed.  I think it would be more useful to default to the first
string rather than the last string.  Here's an example:


typedef enum {

   ABLOB,
   BBLOB,
   CBLOB,
   DBLOB,

   FIRST_BLOB = ABLOB,
   LAST_BLOB  = DBLOB,
   NUM_BLOBS  = LAST_BLOB - FIRST_BLOB +1,

} Blobs;

main()
{
  Blobs  blob,aBlob;

  blob = DBLOB;

  for (aBlob = FIRST_BLOB; blob <= LAST_BLOB; blob++)
  {
     /* do something interesting */
  }
}

If blob is printed with gdb, it will say it is equal to LAST_BLOB instead
of DBLOB.  Also, when aBlob is printed during the for loop, it will
come up with values of FIRST_BLOB and LAST_BLOB instead of ABLOB and DBLOB.
