Not good since that would disable all exercising of DST-related
functionality.

Also not good, from a maintenance standpoint --- we have enough variants
of those files already :-(.

I am inclined to think that treating USE_AUSTRALIAN_RULES as a compile
time option was the wrong idea.  It should be a runtime (GUC) option;
then it can be switched off to run the regress tests, regardless of
whether a particular installation keeps it on by default.
