Therefore,\nimplicit calling conventions and __stdcall are the same, hence\ntemplate redefinition errors occur in the previous gmock_mutant.h\non WIN64.\n\nBUG=173697, 166496\nTEST=media_unittests target builds without template redefinition errors.  With other build errors fixed in privates (ignore C4267 & lift MEDIA...INTRINSICS... definition into yuv_convert.h and use it to not link in methods that use MMX intrinsics), media_unittests executes\n",
