array.c (rb_ary_{times, shuffle_bang, sample}):
removing constant-able macros inside of the loop. a patch from
Masahiro Kanai (CanI) at [ruby-dev:number]. It was found out
and fixed at Security and Programming camp 2009. -
string.c (rb_str_{times, split_m}): ditto.
-
struct.c (rb_struct_{getmember, set, aref_id, aset_id},
{make, inspect}struct, recursive{equal, hash, eql}): ditto.
