[comp.lang.fortran] Detection of aliasses

I am taking this up in private mail with Jim Giles.  However there is one
interesting point remaining:  I wrote about a routine that tried to detect
aliassing of input parameters.  Jim wrote that failure to detect aliassing
in that special case would only influence the efficiency of the code
involved.  However, my opinion is that any attempt to detect aliassing in
a Fortran routine invalidates the code.  I would like to see counter
examples (because on occasion I would like to do it).  So if you have a
portable way to detect aliassing, mail it to me.  Either I will send
back a refutation or I will post the solution.
