The original work on alias analysis by John Carr contained an
implementation of `restrict'. I know, because when we used his work as
an additional patch to the gcc backend (delivered "with" g77 back in
March 1997), we had to be careful to remove the C frontend stuff that
implemented `restrict' from our patch ...
