Because some header files are used for features of a certain OS
(streams are specific to System V Unix) that other OS's (e.g.
BSD/Ultrix) don't have. Supplying the header files without the
functions is meaningless. 

Ad fcntl.h: Ultrix has many many include files both in /usr/include and
/usr/include/sys to be compatible to both BSD and SysV. It looks like
the developers forgot about fcntl.h (Or some bozo rm'ed the symlink on
the disk the distribution tapes where made from :-)
