    No, it's not.

    ISO/IEC 9899:1999(E) §, page 55f:

    5 The type of an integer constant is the first of the corresponding list
    in which its value can be represented.

    Suffix Decimal Constant Octal or Hexadecimal

    none int int
    long int unsigned int
    long long int long int
    unsigned long int
    long long int
    unsigned long long int

    ... so 0x7fffffff is signed int, but 0xffffffff is unsigned int on an
    I32-model system (all Linux systems are I32-model.)
