Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

あ、今思い付きましたが、
void rb_define_method_ARG_VALUES(VALUE klass, const char *name, VALUE
(*func)(int, VALUE *, VALUE))
void rb_define_method_ARG_ARRAY(VALUE klass, const char *name, VALUE
(*func)(VALUE, VALUE))
というのをつくって
rb_define_method(mod, name, fun, ARG_VALUES)
rb_define_method(mod, name, fun, ARG_ARRAY)
と書くようにすれば、ユーザが使う API は増やさなくてもいいかな。

あと、1.8 で
#define VALS_ARG -1
#define ARY_ARG -2
としておけば、1.8 に前方互換性もつけられるからこれなら今実装
してもいいかもしれません。
