Please try changing the following code in `vfe/win/compilers/msvc.h`
(around line 40):

    #undef USE_AVX_FMA4_FOR_NOISE
    #if _MSC_VER >= 1600
      #define USE_AVX_FMA4_FOR_NOISE
    #endif

to:

    #undef USE_AVX_FMA4_FOR_NOISE
    #if _MSC_FULL_VER >= 160040219
      #define USE_AVX_FMA4_FOR_NOISE
    #endif
