Description

r64852以降、Solaris 10 上の Oracle Developer Studio 12.4 にてコンパイルすると、以下のエラーで array.c のコンパイルに失敗します。(r65641 にて確認)

理由は、[Bug #12397] と同じです。
Oracle Solaris Studio 12.4 には、__builtin_constant_p() は存在するため、HAVE_BUILTIN___BUILTIN_CONSTANT_P は 1 になります。しかし、__extension__ は存在しません。(GCC拡張?)
このため、__extension__ が普通の関数と見なされ、syntax error が発生しています。

つまり、r64582 だけでは条件を網羅できておらず不完全であり、__extension__ の有無と(直下のコメント行に書かれているように)statement expression の有無に関する条件も追加する必要があると思います。

[Bug #12397] にも少し書いたように、configure で __extension__ や statement expression の有無をチェックするようにするのがベストとは思います。
