gcc should warn when a function that is declared with __attribute__((pure)) or
__attribute__((const)) is defined in a way that appears to break those
guarantees.

i.e. an __attribute__((const)) function should not be allowed to dereference
pointers or call non-__attribute__((const)) functions (except perhaps
__attribute__((pure)) functions with pointer arguments only allowed to be
references to local variables?); __attribute__((pure)) similarly.
