Is that with the patch?  The errors should be uint to size_t 
conversions.  However, I ran across linker issues becuase of calling 
conventions. Symbols used by the GC, __data_start__ are still exported, 
by the linker scripts, with Win32 calling conventions causing unresolved 
symbol errors when searching for the Win64 version.

Also, is that D1?  I don't recall D2 spitting out as many GC warnings 
but instead had a lot of Windows specific errors.
