[Bug c++/19199] [3.3/3.4/4.0 Regression] Wrong warning about returning a reference to a temporary

Roger, this is a middle-end problem in fond_cond_expr_with_comparision; that is
the routine which makes the invalid transformation.  (It has a similar bug for
MAX_EXPR.)  If the result of the COND_EXPR is an lvalue, I do not believe this
transformation is safe.  As we have no language-independent means of testing
lvalue-ness, I'm not sure that there's a straightforward fix.

Would you care to take a look at this issue?
