Since you said that it compiles correctly in a new solution but not in 
your intended one, it has to be a project setting.  Check your include 
paths (in particular, check the Command Line tab under C/C++ Compiler, 
which shows the inherited and expanded paths as well) and make sure that 
it's not pulling in anything from different VS versions.

If your project is sometimes compiled with other versions of VS, then 
perhaps also check if someone has hard-coded the full path to a VS2013 
or similar header file instead of using relative paths as normal. 
(This'd be unusual, but you never know.)

This is less likely if you tested the old and new solutions on the same 
PC, but in case you did test them on different PCs or different VS 
versions, then also check the VC++ Directories in the Options and the 
INCLUDE environment variable (if it exists, which is rare).
