The manual page at least on Linux suggests that _setjmp() is deprecated but pointed to sigsetjmp(), which seems to offer the same capability: if savesigs (the second arg) is zero, it won't save the signal mask. Maybe that's what we want (and maybe it'll resolve the CI issue on Windows)?

Ah indeed good point! Looks like Windows also doesn't have sigsetjmp but I think having unices use sigsetjmp makes more sense, so I've updated the conditional code to do that.
