	* check.c (gfc_check_loc) : New function
	* decl.c (variable_decl): New variables cp_as and sym. Added a
	check for variables that have already been declared as Cray
	Pointers, so we can get the necessary attributes without adding
	a new symbol.
	(attr_decl1): Added code to catch pointee symbols and "fix"
	their array specs.
	(cray_pointer_decl): New method.
	(gfc_match_pointer): Added Cray pointer parsing code.
	(gfc_mod_pointee_as): New method.
	* expr.c (gfc_check_assign): added a check to catch vector-type
	assignments to pointees with an unspecified final dimension.
	* gfortran.h: (GFC_ISYM_LOC): New.
	(symbol_attribute): Added cray_pointer and cray_pointee bits.
	(gfc_array_spec): Added cray_pointee and cp_was_assumed bools.
	(gfc_symbol): Added gfc_symbol *cp_pointer.
	(gfc_option): Added flag_cray_pointer.
	(gfc_add_cray_pointee): Declare.
	(gfc_add_cray_pointer ): Declare.
	(gfc_mod_pointee_as): Declare.
	* intrinsic.c (add_functions): Add code for loc() intrinsic.
	* intrinsic.h (gfc_check_loc): Declare.
	(gfc_resolve_loc): Declare.
	* iresolve.c (gfc_resolve_loc): New.
	* lang.opt: Added fcray-pointer flag.
	* options.c (gfc_init_options): Intialized
	gfc_match_option.flag_cray_pointer.
	(gfc_handle_option): Deal with -fcray-pointer.
	* parse.c:(resolve_equivalence): Added code prohibiting Cray
	pointees in equivalence statements.
	* resolve.c (resolve_array_ref): Added code to prevent bounds
	checking for Cray Pointee arrays.
	(resolve_equivalence): Prohibited pointees in equivalence
	statements.
	* symbol.c (check_conflict): Added Cray pointer/pointee
	attribute checking.
	(gfc_add_cray_pointer): New
	(gfc_add_cray_pointee): New
	(gfc_copy_attr): New code for Cray pointers and pointees
	* trans-array.c (gfc_trans_auto_array_allocation): Added code to
	prevent space from being allocated for pointees.
	(gfc_conv_array_parameter): Added code to catch pointees and
	correctly set their base address.
	* trans-decl.c (gfc_finish_var_decl): Added code to prevent
	pointee declarations from making it to the back end.
	(gfc_create_module_variable): Same.
	* trans-expr.c (gfc_conv_variable): added code to detect and
	translate pointees.
	(gfc_conv_cray_pointee): New.
	* trans-intrinsic.c (gfc_conv_intrinsic_loc): New.
	(gfc_conv_intrinsic_function): added entry point for loc
	translation.
	* trans.h (gfc_conv_cray_pointee): Declare.
	
	* gfortran.texi: Added section on Cray pointers, removed Cray
	pointers from list of proposed extensions
	* intrinsic.texi: Added documentation for loc intrinsic.
	* invoke.texi: Documented -fcray-pointer flag
