One more thing I ran into:

https://ask.wireshark.org/questions/4725/file-win32mak-not-found-stop

Using Gerald's suggestion worked to get past verify_tools and setup so 
far:

SET INCLUDE=%INCLUDE%;c:\Program Files (x86)\Microsoft 
SDKs\Windows\v7.1A\Include

Should this be included in the dev guide?  I found the answer by 
searching the Internet.  I'm running this setup on Win7 64-bit.
