 Maybe the following?
 from gcc/ChangeLog
 
 2002-09-13  Matt Austern  <austern@apple.com>
 
         * cp/cp-tree.h, cp/tree.c: New function non_cast_lvalue_p.
         * cp/call.c: Change call-by-const-reference mechanism to use
         non_cast_lvalue_p when deciding whether the create a temporary.
         We need a temporary when passing, e.g. (long) x by const ref.
         * testsuite/g++.dg/other/constref[12].C: New, regression tests for
         passing a cast expression to a function by const reference.
 
 
 I think this entry should go into cp/ChangeLog ...
 Gaby could you fix that?
