Native(C++) build throws unexpected errors

Hi All.This is the first time I am trying to use Gradle to see if it matches our needs.We are building C++ libs on Win.MSVC120 64bit.Now,we have tried to build a lib which builds fine via VisualStudio.But setting the same compiler options using Gradle we are getting a compilation error for a method where we reinterpret cast of function pointer:

error C2664: ‘void gluTessCallback(GLUtesselator *,GLenum,void (__stdcall *)(void))’ : cannot convert argument 3 from ‘GLvoid (__cdecl *)(void)’ to 'void (__stdcall *)(void)'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast

The strange thing here is that in the code we do use reinterpret_cast<>() method so it is not clear why that error persists.It also compiles fine using the same toolchain via MSVC.And therefore I wonder if it has something to do with Gradle itself,or something wrong with our settings.
Here is the gradle.build

apply plugin: 'c’
apply plugin: ‘cpp’

model{

  /* Toolchain  */
  toolChains{
      visualCpp(VisualCpp){
	     installDir "C:/Program Files (x86)/Microsoft Visual Studio 12.0"
		 
	  }

  }
  /*  Platforms */
  platforms {
        x64 {
            architecture "x86_64"
        }
  }
  /* Build types  */
  buildTypes {
        debug
        release
  }
  
  
  components {
      
      MyLib(NativeLibrarySpec){
	     binaries.all {
	         cppCompiler.args  '/TP','/WX-','/GS','/W3', '/Gd','/MDd','/RTC1','/EHsc','/fp:precise','/errorReport:prompt','/Zc:forScope','/Zc:wchar_t','/DWIN32','/D_CRT_SECURE_NO_WARNINGS','/D_LIB' ,'/DUNICODE' ,'/D_UNICODE'
         }
	     sources {
            cpp {
               source {
                             srcDir "MyLib/src/"
				 exclude "**/*.xml"
				 exclude "**/*.txt"
				 exclude "**/*.vcxproj"
				 exclude "**/*.directory"
				 exclude "**/*.vcxproj.user"
				 exclude "**/*.vcxproj.filters"
               }
			   exportedHeaders {
			            srcDir "C:/Program Files (x86)/Windows Kits/8.1/Include"
			            srcDir "ThirdParty/glm-0.9.7.0/glm" 
			            srcDir "ThirdParty/boost_1_58"
                                srcDir "MyLib/include"
				    srcDir "ThirdParty/glew-1.10.0/include"
               }
            }
         }
	  
	  }
	  
  
  }
}

Appreciate any help here.Thanks!
