--- Comment #27 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-09-04 16:47:47 UTC --- (In reply to comment #25) Your proposed patch from comment 25 appears to be working under clang 4.0 of Xcode 4.4. The configure test is properly run against the newly built compiler and fails against the system assembler as expected on darwin12. Thanks.
