Subject: 	* cppfiles.c (redundant_include_p): Provide length of token to
 	cpp_defined. 	* cpphash.c (_cpp_make_hashnode, _cpp_lookup_slot):
 Hash 	values are unsigned int. 	(_cpp_lookup, _cpp_lookup_slot): Do
 not calculate the length. 	(_cpp_lookup_slot): Do not calculate the hash,
 either. 	* cpphash.h: Update prototypes. 	* cpplib.c (do_define,
 do_undef, do_pragma_poison, do_assert): 	Hashes are unsigned int. 
 Calculate hash here, pass by value 	to _cpp_lookup_slot.
