Problem when building harmony on 64bit Windows

[kent qi]

Hi, colleagues,
   When building harmony on 64bit Windows, I met such problem:

build.native.link:
      [cc] 0 total files to be compiled.
      [cc] Starting link
      [cc]    Creating library jitrino.lib and object jitrino.exp
      [cc] LINK : error LNK2001: unresolved external symbol _CorDllMain
      [cc] jitrino.dll : fatal error LNK1120: 1 unresolved externals


   Does anyone know how to fix it? Thanks a lot!!
