GCCでリストイテレータをコンパイルするときのテンプレートコンパイル時エラーGCC

Question

このコードは、GCC ARMでコンパイルすると多くの頭痛を与えます。私はそれをMSVC++コンパイラ2010でうまく使っています。コンパイルエラーは次のようになります。

エラー1エラー：予期した ';'前に '私' C：\ Users \ Ryan \ Desktop \ droplets \ source \ MultiList.h 62

GCCを使用してテンプレートコードをコンパイルできないのはなぜですか？

それがぎっしりいっぱいo'errorsであるため、コンパイルされません。

使用-Wallとその不満が何であるかを理解しています。なぜMSVC はではないのですか？
