Bugzilla Bug 72909

In my environment, the following error occurs and fails to compile.
I think that this problem relates to gcc 3.4.x.

Yes, it's related to gcc34. All sources with chasen
have this problem (I made shinji package, available
at http://sourceforge.jp/projects/shinji/ yesterday,
and it also contains this bug)

Probablly

+	keys[size] = const_cast<char*>(key.data());

is better?

I made a revision bump, which includes Yuta's patch.
