IA64 libc.so always depends on libunwind?

Yes, but libgcc_eh.a is the archive version of libgcc_s.so, so you
_do_ link in the unwinder into each and every binary.  Except that
with libunwind, we don't want libunwind as part of libgcc_eh.a.

  HJ> For C, libgcc_s.so is not needed.

  HJ> Do all executables need exception-handling support on ia64?

No, it has nothing to do with ia64.  It has everything to do with
libc now using exception-handling support (via the cleanup-handlers).
