It worked fine, then I downloaded the new Universal Headers from Apple''s Developer web site, and now it doesn''t work. It''s erroring out on some enums in MacErrors, saying "Illegal overriding". MacErrors.h is coded with #ifdefs so that it only loads once. They''ve also enabled #pragma once on CodeWarrior, so there are redundant checks against it being loaded twice, and I can''t find anywhere else where the error constants are defined. Anyone have any ideas on why it thinks the values are getting redefined?

Duh. I forgot to rebuild the precompiled headers after updating the universal headers.
