----------------------------------------
r45488以降、Solarisにて、`ext/readline` が下記のようにコンパイルエラーになります。コンパイラは SolarisStudio 12.3 です。
readline 6.2 との組み合わせになります。

`ext/readline/extconf.rb` の `readline.have_type("rl_hook_func_t")` に、 `rl_hook_func_t` は存在するはずにもかかわらず、失敗しているのが原因のようです。

`extconf.h` と `mkmf.log` を添付します。
