No point in doing this -- hexadecimal literals are unsigned by
definition. File a compiler bug if you see them interpreted otherwise.
Not unless they have to be (see C99 if you don't believe me... on a
I32LP64 system for example, 0x7fffffff is signed int, 0x80000000 is
unsigned int, 0x100000000 is signed long).
What is this supposed to solve in the first place?
