Issue
Today had a customer who was facing warning: RC4005/C4005 after installing VS2013 Update 3. They also had installed the Windows 8.1 SDK. Any new project created in the IDE showed these symptoms so this was not caused by existing code.
Cause
It turned out that his include file settings in project properties was causing this. It was missing a critical include…
$(WindowsSDK_IncludePath)
We added above include as illustrated below and the warnings (RC4005/C4005) went away…
Hope this helps save your time.
