 Changes made to vs2015 build
 
-1. allow solution to be used in place
+Changes
+1. Removed the use of /FS.
+2. Allow multi-processor compilation.
 
-To Do
+Questions
 
-1. win\share\tiletxt.c is copied from win\share\tilemap.c ... use tilemap.c instead directly.
+1. Why is /Gs used?  This initiates stack probes for every function call (not just functions that use more then 4k)?
+2. Why is /Oi- used?  This turns off compiler intrinsics.
+3. Why is /FS used?  This forces serialization of writes to PDB.  This really isn't needed.
+4. Why are we disabling optimizations for release builds?
+5. Why are we omitting frame pointers?  Makes debugging harder.  Crash dumps less usefull.
+6. Why are we forcing function level linking?
+7. Why are we turning off intrinsics (again)?
+8. Why are we enabling additional security checks? (SDLCheck)
+9. Why are we using string pooling?
+10. Why do we turn off multi-processor compilation?
