[libunwind] Missing error functions

[Rob Faught]

When I link to libunwind-ia64.a (0.93) on HPUX IA64 I get the following 
errors. I see where the functions
are called but not where they are defined. I am missing something?

ld: Unsatisfied symbol "unw_cursor_t_is_too_small" in file 
../tools/lib/libunwind-ia64.a[mi-init.o]
ld: Unsatisfied symbol "unw_hash_index_t_is_too_narrow" in file 
../tools/lib/libunwind-ia64.a[global-ia64.o]
2 errors.
