# NOTE: carlton/2003-01-16: hairyfunc5-6 fail on GCC 3.x (for at least
# x=1 and x=2.1).  So I'm modifying print_addr_2 to accept a failure
# condition.  FIXME: It would be nice if the failure condition were
# conditional on the compiler version, but I'm not sufficiently
# motivated.  I did hardwire in the versions of char * and int *,
# which will give some compiler-specificity to the failure.
