Hard to answer that question for certain. I had a hunch shortly
after I sent this message, though: On the (relatively old) Linux
machine that we have at AdaCore, I can't link against the system
libunwind. I think it's a linker bug, as the linker is complaining
about missing symbols, whereas I can see them fine. These are
protected symbols, but they are there. No problem with GNU
libunwind. But I did send a message to Jan asking him if he could
test on a newer distro, and he said that he'd get back to me
as soon as he has time.
