Code review comment for lp:~ab-tools/widelands/msvs2010-compilewarnings

I get a some compiler errors concerning _strdup. It is not defined on my system.

I am not too fond with the arbitrary type casting all around. The proper fix would be to track down where the wrong types are used and fixing this throughout the code. If a type is necessary it should only be done exactly once. I feel uneasy just casting around to shut up the compiler like that.
