Log message:

ircd.c must include sys/resource.h in order to define RLIMIT_CORE.  If
RLIMIT_CORE is not defined, set_core_limit() never gets defined or called.
If set_core_limit() never gets defined or called, ircd never raises the
soft limit on cores.  If the soft limit on cores never gets raised, ircd
never dumps core.  If ircd never dumps core, well, we can't debug ircd,
now, can we?  :)
