Sure there is. The code in 7.1.x needs to have USE_AUSTRALIAN_RULES
evaluate to "true" (there is an #if, not #ifdef), so you should set it
equal to one (rather than just have it exist).
I think that "-DUSE_AUSTRALIAN_RULES=1" should work; you can set it as
CFLAGS+=... in Makefile.local, or continue to try to get an environment
variable to do what you want (I do not use that technique myself, so
can't help with the nuances, but maybe export CFLAGS="..." with some
quotes will do it).
