Solaris 10 上にて、Sun(現Oracle)がOSのおまけとして提供しているフリーソフト集に含まれている、とても古いバージョンのgccにてrubyをコンパイルすると、rb_mjit_min_header-2.6.0.h の作成に失敗してエラーになります。
（r63531にて確認）

gccのバージョンは以下のとおりです。

~~~
$ /usr/sfw/bin/gcc --version                                 
gcc (GCC) 3.4.3 (csl-sol210-3_4-branch+sol_rpath)

今さらgccバージョン3系を使うほうが悪いのは重々承知ですが、念のため記録だけしておきます。
