I don't think you've adequately justified having OS-specific versions of
all the setjmp/longjmp files, as opposed to having e.g. defined __SHSTK__
&& defined SHADOW_STACK_POINTER_OFFSET && defined FEATURE_1_OFFSET
conditionals in the OS-independent files (which looks more like the actual
condition that should be relevant here).
