--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
I agree that huge decimal numbers can be hard to read (not just in this message
but in all others that print them).  I have been thinking about an enhancement
to the pretty printer that would make it possible to use symbolic constants
like INT_MAX or use simple expressions involving them like CHAR_MAX + 2.  Using
hexadecimal for very large numbers might be worth considering as well.

That said, unless this particular instance of the warning is a false positive,
I would view this report as an enhancement request rather than a regression. 
Can you explain why you marked it as such?
