4.2 signals broken?

[Charles LaBrec]

I don't have access to a System III/V machine, so correct me if I'm
wrong, but isn't Sys III/V non-backward compatible to V7?  The tty
driver, the fcntl() call, and changing the names of some library routines
comes to mind (index, rindex, strn???).  Is it possible to completely
emulate V7 behavior in Sys III/V?  If not, then what 4.2 did to signals
seems to be analogous.
