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=" "

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

status=267 stdout=" "

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.
