These are not functions I was talking about. I was talking about the
unw_* family of functions, see "man unw_getcontext", for example.
These functions are declared in libunwind.h, not unwind.h. This header
seems to be a drop-in replacement for /usr/local/include/libunwind.h,
which comes from devel/libunwind, but unlike the port the base header
does not have an accompanying shared library.
