o Add typedefs for size_t and ssize_t.
o Add typedefs for gid_t, off_t, pid_t, and uid_t in the non-standards case. o Add struct iovec (also defined in <sys/uio.h>). o Add visibility conditionals to avoid defining non-standard extentions in the standards case. o Change spelling of some types so they work without including <sys/types.h> (u_char -> unsigned char, u_short -> unsigned short, int64 -> __int64, caddr_t -> char *) o Add comments about missing restrict type-qualifiers and missing function.
