Since this problem afflicts many applications (not just grep), the 
preferred solution would be to fix z/OS so that a process terminated by 
a signal has the exit status corresponding to the signal, even if the 
signal arrives during calls by 'exit' to functions registered by 
'atexit'. This is required by POSIX[1] and is what other systems do. Is 
that something you could start the ball rolling on? (I don't use z/OS 
and so cannot file bug reports for it.)

I don't see any straightforward change to 'grep' that would work around 
the z/OS problem. However, if you can think of a change, please let us know.

Also, could you please let us know the z/OS version so that I can 
document this portability problem in Gnulib? Thanks.
