Bug #5464: compile error in vm_eval.c

Solaris 10 にて Fujitsu C Compiler Version 5.6 を使ってtrunkをコンパイルしたところ、以下のコンパイルエラーが出ました。

"./vm_eval.c", line 275: error: initialization: constant expression is expected for variable: `args'

このコンパイラでは、Cの配列の初期値としてコンパイル時に確定するものしか使えないようです。
1要素ずつ代入するようにするパッチを添付します。他の環境でも問題ないと思います。
