variable of a class object instead of a class variable for metadata. This change is crucial for ruby 1.8 and applying it also to the trunk will assure compatibilities. * ext/digest/md5/md5init.c (Init_md5): Ditto. * ext/digest/rmd160/rmd160init.c (Init_rmd160): Ditto. * ext/digest/sha1/sha1init.c (Init_sha1): Ditto. * ext/digest/sha2/sha2init.c (Init_sha2): Ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@11133 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
