[howarth at nitro dot med dot uc dot edu]

------- Comment #6 from howarth at nitro dot med dot uc dot edu  2008-08-11 17:34 -------
Is there a particular revision that this appeared in? I built a svn pull from
gcc trunk on 20080808 (using the optabs fix that has since been checked in)
against
gmp 4.2.3 on i686-apple-darwin9 and didn't see any build issues.
