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. */
