c - gcc48(从 Homebrew 软件下载)找不到stdio.h

Question

我在 OSX Yosemite 上工作，我从 Homebrew 软件安装了 gcc-4.8。

以下程序在编译时失败(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，但看在上帝的份上，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。
