Doesn't your version of gcc output:

warning: this decimal constant is unsigned only in ISO C90

Try -std=gnu99 and you might get a different result.

In C90 mode, GCC treats 2147483648 as an unsigned int. It then negates it,
before casting to a long long, and -2147483648 is the same as 2147483648 in
only 32-bits.
