C 从Visual Studio 2013切换回2012时出现Intellisense错误

我有一个OpenGL应用程序，在使用Visual Studio 2013时运行时没有任何错误。现在，我的VS2013许可证已过期，我切换回VS2012。当我在VS2012中打开该项目时，会出现大量错误：

所有这些错误都属于这段代码：

void setColor()
{
    switch (currentColor)
    {
    case COLOR_RED:
        if (lightOn) {glLightfv(GL_LIGHT0, GL_DIFFUSE, new GLfloat[] { 1.0, 0.0, 0.0, 1.0});}
        else glColor3f(1.0, 0.0, 0.0);
        break;
    case COLOR_GREEN:
        if (lightOn) glLightfv(GL_LIGHT0, GL_DIFFUSE, new GLfloat[] { 0.0, 1.0, 0.0, 1.0});
        else glColor3f(0.0, 1.0, 0.0);
        break;
    case COLOR_BLUE:
        if (lightOn) glLightfv(GL_LIGHT0, GL_DIFFUSE, new GLfloat[] { 0.0, 0.0, 1.0, 1.0});

我首先想到的是头文件弄得一团糟，所以我把它们按各种可能的顺序排列，但这些愚蠢的错误仍然存在。

Intelissense在项目文件*.sdf中保存了一些信息，请尝试将其删除，然后重新打开并重新编译项目。不，不幸的是，它没有工作。当我删除.SDF文件并清理项目时，我仍然会遇到同样的错误。注意到，您使用的是C++，莱特？这样的构造：新的GLfloat[]{0.5,0.0,0.5,1.0}是非法的。通常创建这些数组，作为静态大小数组，初始化列表GLfloata[]={0.5f，0.0f，0.5f，1.0f}；glLightfvGL_LIGHT0，GL_漫反射，a；，或者动态地，然后，用值填充它们。这实际上是我的一个朋友建议的，这是有道理的，这是非法的。然而，当我在VS2013上运行这个项目时，它并没有引起问题。是因为他们使用的编译器不同吗？这会改变语言的可接受语法吗？我按照你告诉我的方式改变了代码，现在一切正常。非常感谢。但我仍然对这种行为感到困惑。如果你知道是什么原因，请告诉我。
