Browse Source 
* cygheap.cc (cygheap_init): Initialize rlim_core to RLIM_INFINITY.
	* exceptions.cc (stackdump): Drop extern declaration of rlim_core.
	Refer to cygheap->rlim_core instead.
	(exception::handle): Disable stackdumping if cygheap->rlim_core is 0.
	Don't set WCOREDUMP flag in exit code, if cygheap->rlim_core is 0.
	(sigpacket::process): Ditto.
	* resource.cc (rlim_core): Remove.
	(getrlimit): Fetch RLIMIT_CORE value from cygheap->rlim_core.
	(setrlimit): Store RLIMIT_CORE value in cygheap->rlim_core.
