mac下用brew更新了gcc，有很多头文件不能用了！
如题
比如说写一个helloworld
1 #include <stdio.h>
2 #include <stdlib.h>
3 int main(){
4 printf("Hello World!");
5 return EXIT_SUCCESS;
6 }会出现以下错误
night:test mac$ gcc helloworld.c -o helloworld
In file included from helloworld.c:1:
/usr/local/Cellar/gcc/8.1.0/lib/gcc/8/gcc/x86_64-apple-darwin17.5.0/8.1.0/include-fixed/stdio.h:78:10: fatal error: _stdio.h: No such file or directory
#include <_stdio.h>
^~~~~~~~~~
compilation terminated.我看了这个路径下的这个文件，它里面确实加了一个下划线
1 /* DO NOT EDIT THIS FILE.

3 It has been auto-edited by fixincludes from:

5 "/usr/include/stdio.h"

7 This had to be done to correct non-standard usages in the
8 original, manufacturer supplied header file. */
