Description :
Integer constants are de facto limited to int64 by Cil. Should use Big_int to accept any constant.
Steps To Reproduce :
void main(void) { /*@ assert 0xfffffffffffffffff == 0xfffffffffffffffff; */ }
$ frama-c a.c a.c:1:[kernel] failure: Cannot represent on 64 bits the integer 0xfffffffffffffffff
