  Log Message:
  -----------
  Diagnosing the Future Keywords

The patch diagnoses an identifier as a future keyword if it exists in a
future language mode, such as:

int restrict;

in C modes earlier than C99. We now give a warning to the user that
such an identifier is a future keyword. Handles keywords from C as well
as C++.
