--- Comment #6 from Gary Funck <gary at intrepid dot com> 2012-12-02 21:48:28 UTC --- "This isn't a bootstrap since you pass --disable-bootstrap to configure ..." Agreed. I didnt' know how to classify this problem. Since the version of 4.7.0 that I used appears incompatible with the version of gmp that we build as a pre-requisite, I will try a 4.6 compiler and see if I get a different result.
