* io.c (argf_seek_m): wrong calling sequence of rb_io_seek().
* parse.y (cond0): no special treatment of string literal in condition. * math.c: add acos, asin, atan, conh, sinh, tanh and hypot to Math. * configure.in: check hypot availablility. * missing/hypot.c: public domain rewrite of hypot. * parse.y (warn_unless_e_option): warning condition was wrong. * parse.y (warning_unless_e_option): ditto. * enum.c (enum_all): new method 'all?', which returns true if block returns true for all elements. * enum.c (enum_any): new method 'any?', which returns true if block retruns true for any of elements. * marshal.c (marshal_load): do not give warning unless explicitly set to verbose. * eval.c (rb_exit): give string value "exit" to SystemExit. * ruby.c (proc_options): -v should not print version if proc_options called via moreswitches(). * parse.y (stmt): while/until modifier must work for empty body. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@1241 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
