st_compare_func_t, st_hash_func_t and st_each_func_t. * st.h, st.c: Do explicit function declarations and do not rely on implicit declarations. On such platforms as IA64, int argument values are NOT automatically promoted to long (64bit) values, so explicit declarations are mandatory for those functions that take long values or pointers. This fixes miniruby's coredump on FreeBSD/IA64. * class.c, eval.c, gc.c, hash.c, marshal.c, parse.y, variable.c: Add proper casts to avoid warnings. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@3303 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
