This is frequently poorly implmented.  I use local variables
in procedures mainly to save a little stack space (although
I don't do it very often).  In the following example:

proc()
   {
   if (...)
      {
      int i;
      ...
      }
   while (...)
      {
      int j;
      ...
      }
   }

the variables 'i' and 'j' may use the same location on the stack
frame.  Of course, this is a trivial example.  Some compilers, however,
simply give all local variables their own location.  I don't understand
that kind of laziness.
