    _______________________________________________________

Details:

It looks like the value of .SHELLSTATUS is not always set correctly when the
$(shell …) command is terminated by a signal.  

Here’s a Makefile which demonstrates this behavior:

STDOUT := $(shell kill -s SEGV $$$$) 
$(info status=$(.SHELLSTATUS) stdout="$(STDOUT)") 

all :
        @echo "done"

On Debian 8 Linux and OSX 10.12.2 using gmake 4.2.1 I get the following
output:

status=0 stdout=" "
done

On Windows 10 also using gmake 4.2.1 I get the following output:

status=267 stdout=" "
done

On Linux and OSX I would have expected the behavior I'm seeing on Windows 10,
where gmake receives a non-zero exit value from the recipe.

Thanks!
