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