I think you are talking about something different.

In particular, this is work that Dan said he could not complete for

If-conversion has been submitted.  There are non-trivial issues with the 
patch according to Richard.  If this gets done before Septemberr 5th, I 
don't object.  Otherwise, we don't need this before GCC 3.5.
