For extra confusion, unwind.h is also provided by the various libunwind implementations, but it provides a different API. And in some cases, they ship unwind.h but not libunwind.h, and then this check incorrectly detects as positive... This is a separate commit because it should probably be backported. (A larger rework of the backtrace configure option is following.) Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
