Yes, I shouldhave mentioned that.  The standard requires certain things
to be documented, and the standard implicitly requires such
documentation to be accurate.

The behavior of signed overflow is undefined.  An implementation could
document that signed overflow always follows the common wraparound
semantics.  If it behaved differently in some cases, that would be a bug
in the implementation, but not a violation of the standard.

Upthread you wrote that:

    ... modern philosophy seems to suggest that the fact that the
    Standard regards something is undefined should negate even parts of
    the compiler's own documentation which would otherwise describe the
    behavior.

That's the part I was disagreeing with.  The standard doesn't require
implementations to follow their own *additional* documentation, but it
doesn't override any such documentation.
