Compiling with Clang 3.9.0 on Windows 10

I’ve been able to use Clang 3.7.0 to compile and link on Windows 10 from the Command Prompt pretty well, but when I try it on version 3.9.0, I get an Linker error saying that it can’t find corecrt.h. Is this a serious problem with compatibility, or is corecrt.h a Windows header file that I need to have on my own computer and it’s because I don’t have it that I get that error?

You may be missing an IncludePath.

Also, this is for LLVM discussions.
