- Add <sys/param.h> and <limits.h> where required (do not depend on other headers pulling it in). - __dead -> __dead2 - #if defined() -> #ifdef - Remove ugly PRIu64 macros and use %llu w/ (unsigned long long) cast. All changes looped back to OpenBSD (where applicable) for easier sync in the future. Requested by: bde Approved by: bms(mentor)
