* findvar.c (extract_signed_integer): Cast *p to LONGEST before doing 

the xor and subtract.  Otherwise it will not sign extend if the type
	of LONGEST is larger than int.
	* cp-valprint.c (cp_print_class_method):  Inhibit core dump if
	domain is an undefined cross reference.
	* valops.c (call_function_by_hand):  Set real_pc to correct
