In at least a significant number of these cases, the "old binaries" would be 4.3 binaries on a VAX. Look at rev. 1.1 of syscalls.master and notice how many of them were already marked COMPAT in 4.4-Lite. I believe creat, wait, sigvec, sigblock, sigsetmask, and killpg were also COMPAT_43 in Net/2. creat() has never been a syscall in the entire life of FreeBSD, but we're still carrying around the code to implement it for "compatibility" with old VAX binaries. -GAWollman
