I would ignore this claim.  I have years of experience with error
messages with numbers in g++, my_friendly_abort.  The only pain about
it is having to update the place to get a new number from, when you
allocate a new number.  The number have been consisent across releases
since its introduction, and they have never needed any maintenance
(save for the rarity when someone put in a 999 because they didn't
allocate a number yet, or the rarity when we tried to reuse a number
(don't do that), or a random typo in the number).
