I am experimenting to build Firefox using VS14 (which is in CTP2 right now). Microsoft has announced that they are splitting the C Runtime (CRT) to 3 separate files, instead of a single msvcr140.dll.

Older version of the MSVC DLLs to be packaged seems to be determined by MSVC_C_RUNTIME_DLL and MSVC_CXX_RUNTIME_DLL. While the latter one is still msvcp140.dll in VS14, which DLL files has to be packaged for MSVC_C_RUNTIME_DLL? From the blog post it seems to be vcruntime140.dll and desktopcrt140.dll, as Firefox is a desktop app. 

I wonder if MSVC_C_RUNTIME_DLL has to be expanded to include multiple MSVC DLLs due to this change.

It should be all 3 files are needed.

I can confirm all 3 files are needed at least with vs2015 preview.
