gcc48（自制软件下载）找不到stdio.h

Question

我正在开发 OSX Yosemite 并且我从自制软件安装了 gcc-4.8。

以下程序编译失败（例如gcc-4.8 main.c）：

#include <stdio.h>    

int main(void)
{
    printf("hello world");

    return 0;
}

错误：

main.c:8:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
                   ^
compilation terminated.

和

 $`gcc-4.8 -print-prog-name=cc1` -v

现在我知道我可以通过 -I /path/to/directory 让编译器找到正确的头文件，但天哪，这是 stdio.h！我不想为愚蠢的小程序做这件事。我该如何修复这个缺陷？

我最终删除了 brew formula 并重新安装了它。它现在可以工作了，我仍然不清楚它何时何地被破坏。

编辑原来这个问题已经发生了好几次了。每次我升级 OSX 或 Xcode.

时都会发生这种情况
