I’m still having this issue as well with the preview 2 build. and the preview 2 build does not seem to have the /ZmXXX line that people mention below. (Noticed it was removed in the change notes on github)
I’m having this issue when building the UE4 Source itself.
Ok so i repaired the VS2013 and added the /Zm lines that were taken out in the preview 2 in files UWPToolChain.cs and VCToolChain.cs and compiling now seems to be compiling fine now.
