I'm having second thoughts on tweaking the default behavior of GSL's configure on OS X. Use 'CC=clang ./configure' is such an easy fix to tell folks, and I think it's rather un-GNUish to default to the non-GNU compiler. And I'd still love if someone nailed down the actual problem since presumably something numerical is broken at -O2 on that compiler. - Rhys
