build failure after switching to vs2013

[Pete Brunet]

I was able to build 9 OK then I switched from VS2010 to VS2013 and now
get the following.  I tried hg tpull -u but that didn't help. 

Is there something I need to do besides installing VS Pro 2013 with
Update 4?

$ make images 2>&1 | tee make-64.log
