Fix compilation errors in 32-bit debug

Oops, sorry.  I've been using x64 debug for a while so I missed this.  Darn.

See hrydgard/ppsspp#1678.  But x64 does work, not sure what that's about.

Alternatively, I can undo the cityhash thing, not sure if you use edit and continue with this code (I don't.)
