--- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to s.bauroth from comment #7) > > The type of an integer constant is the first of the corresponding list > > in which its value can be represented. > These kind of sentences make me think gcc's behaviour is wrong. The number > can be represented in 32 bits. No it can't. A few paragraphs above the text I quoted last time it says:L "An integer constant begins with a digit, but has no period or exponent part. It may have a prefix that specifies its base and a suffix that specifies its type." So the - sign is not part of the constant. The constant is 2147483648 and that doesn't fit in 32 bits. So it's a 64-bit type, and then that gets negated. That has been explained several times now. "I don't understand C and I won't read the spec" is not a GCC bug.
