BSD supports funopen() which allows the user to create handles for
arbitrary stream types.

wordexp/wordfree are in 5.0, so they will probably be backported to 4.*
at some point.

User applications should not need to know about FreeBSD's shadow
password style, so that shouldn't really matter.

uname() is the correct function name (the data is returned in a struct
utsname), and BSD supports it.

BSD has supported large files far longer than Linux has.  fseeko and
ftello are the functions you should use.  fseeko64 is sort of redundant :)
