Fixing news for 4.2BSD is nontrivial.  It involves using setjmp/longjmp
and setting a flag so that the longjmp will only be done when there is
something ready to catch it.

In the meantime, for those of you upgrading to 4.2BSD, here are two things
you can do.

(1) Use your 4.1BSD binary of readnews.  I know this works for a 4.1c binary,
and it should work for a 4.1 binary, but I haven't tried it.  This works
only if you have compatibility mode compiled into the kernel.

(2) Create a signal.o file from your old 4.1 libc.a or signal.s, using the
4.1 signal system call number (48).  Load with signal.o before libc gets
called.  This will invoke the 4.1 compatibilty mode signal mechanism in
the kernel, and allow you to recompile.  I haven't tried this.
