Once I updated my environment to account for DSTROOT/SRCROOT and so forth, everything worked amazingly well. However, I get the following link error: 1>objc-typeencoding.m 1>Generating Code... 1>Compiling manifest to resources... 1>Microsoft (R) Windows (R) Resource Compiler Version 6.1.6723.1 1>Copyright (C) Microsoft Corporation.

Since they relate to DYLD load/map/unmap they are probably not needed for the Windows build at all. These symbols are used in both the objc-runtime-new.m and objc-runtime-old.m implementations: 1. map_images 2. unmap_images 3. load_images I ended up bracketing these three functions inside a "#if !TARGET_OS_WIN32/#endif", and everything then built fine. Since these functions appear to be unused on the Windows build, I assume this change is correct, however I wanted to see if this was the correct course of action, or if perhaps a Windows-specific build file might be missing in the distribution?
