Mod isn't supported

[lwli11]

The % operator is not supported, and the error message isn't explanatory:

The minimal program example capturing this is:

int mod(int n)
/*@
requires n>=0i32; n<MAXi32();
@*/
{
        return n % 2;
}

Which returns:

cn mod.c
[1/1]: mod

This one is very close to being fixed.
