<chuckle> I know, I know. On Mac OS the first trip through <stddef.h> doesn't define offsetof. Or said differently, offsetof doesn't get defined if any of __need_* are defined. The first trip creates the desired macros and #undefines the request. The second trip creates offsetof. <shrug> -Howard _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
