Re: RFA: Adding a location_t (or pointer) to tree_exp for 3.4 only.

Sure.  But previously the code must have been looking for CALL_EXPR
by virtue of a switch/test/whatever.  This is obvious because we 
were not aborting in get_callee_fndecl.  I expect this to change 
not at all.

I would expect wrapping with WFL would not change this at all.  I
would expect that we'd simply call expand_expr one extra time, and
the subsequent recursion on the contained call_expr to do exactly
what we would have done before your change.

So your comment re get_callee_fndecl continues to make no sense.


PS: Your response should include a *detailed* explanation for how
we would get into the situation that you describe.
