New obstack_next_free is not an lvalue
New obstack.h casts obstack_next_free to (void *), resulting in it
being a non-lvalue, and warnings on pointer arithmetic.
gcc/
* gensupport.c (add_mnemonic_string): Make len param a size_t.
(gen_mnemonic_setattr): Make "size" var a size_t. Use
obstack_blank_fast to shrink obstack. Cast obstack_next_free
return value.
gcc/objc/
* objc-encoding.c (encode_aggregate_within): Cast obstack_next_free
return value.
