Subject: [ruby-dev:50368] [Ruby trunk Bug#14199] eval_error.c compile error with Oracle Solaris Studio (Oracle Developer Studio) 12.4 on Solaris 10

Issue #14199 has been updated by usa (Usaku NAKAMURA).


とりあえず、ここ(redmine)で該当リビジョンを表示し、「関連するチケット」の「追加」をしてやれば、ここでの見た目上だけは、なんかうまくやったように誤魔化すことができます :)

# なお将来バックポートが必要とかになったときにメンテナが助かるので割と推奨

おそらく r61154 以降、Solaris 10 上の Oracle Solaris Studio 12.4 にて、
下記のエラーにより eval.c のコンパイルに失敗します。

write_warn, write_warn2, write_warn_str の各マクロ定義中にて、
三項演算子「? :」の右側の2項（「AAA ? BBB : CCC」の BBB と CCC）の型が不統一、
具体的には void型を返す関数 と VALUE型を返す関数が混在しているのが原因です。
