This is a link-time error check, so it's intentional that
unw_hash_index_t_is_too_narrow isn't defined.  Perhaps the real
problem is that compiler optimizations have been turned off?  Without
a sufficiently high optimization level, the compiler won't recognize
the call as dead code and then you'd get a link time error.
