c程序为什么在windows里运行可以，到linux下就有错误？帮我一下
在线等待，路过的请留下点建议，呵呵，谢谢了！错误如下：
hao@hao-laptop:~/c$ gcc -o procpcb procpcb.c
procpcb.c:24: 错误： expected ‘;’, ‘,’ or ‘)’ before ‘&’ token
procpcb.c:29: 错误： expected ‘;’, ‘,’ or ‘)’ before ‘&’ token

procpcb.c:121: 错误： expected ‘;’, ‘,’ or ‘)’ before ‘&’ token
procpcb.c:139: 错误： expected ‘;’, ‘,’ or ‘)’ before ‘&’ token
procpcb.c: 在函数 ‘main’ 中：
procpcb.c:186: 错误： 在 C99 模式之外使用 ‘for’ 循环初始化声明
procpcb.c:175: 警告： ‘main’ 的返回类型不是 ‘int’
