B.3.1.3 bsd_signal
Applications are recommended to use the sigaction( ) function
instead of this function.
There are some other widely used interfaces also removed, including
gethostbyname(), vfork(), and usleep(). I have to admit to having
largely ignored POSIX for several years, even though I'm still formally
on the committee and occasionally throw in a hand grenade.
The intent seems to be to unburden minimal implementations, but a "real
Unix" can hardly do without these for a very long time.
