I think you are confused over the rules for the type of an integer constant. Assuming 32 bit ints, the type of 0x7fffffff is "int", but the type of 0x80000000 is "unsigned int". Thus ~0x8000000 is 0x7fffffff, *not* 0xffffffff7fffffff as you claim. Note also that the rules for decimal constants are different to those for octal and hexadecimal.
Latest news from the linux-kernel list: we compile with --enable-64-bit-bfd (Debian does this by default, it seems). So, we're talking 64-bit. In 64-bit, ~0x80000000 is 0xffffffff7fffffff.
