/* The name of the ppc_thread_state structure, and the names of its
members, have been changed for Unix conformance reasons. The easiest
way to have gdb build on systems with the older names and systems
with the newer names is to build this compilation unit with the
non-conformant define below. This doesn't seem to cause the resulting
binary any problems but it seems like it could cause us problems in
the future. It'd be good to remove this at some point when compiling on
Tiger is no longer important. */
