交叉编译client程序出错，望高手赐教！

Question

程序如下：#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
#include <netdb.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <sys/socket.h>
//#include <sys/wait.h>
#include <unistd.h>
                                                                                             
#define PORT 3490
#define MAXDATASIZE 100  
                                                                     
int main(int argc, char *argv[])
{
int sockfd;
int numbytes;
char buf[MAXDATASIZE];
struct hostent *he;
struct sockaddr_in their_addr;
                          
if (argc!=2)
   {
    fprintf(stderr,"usage:client hostname\n";
    exit(1);
   }
if ((he=gethostbyname(argv[1])) ==NULL)
   {
   perror("gethostbyname";
   exit(1);
   }                                                                                                  
if((sockfd=socket(AF_INET,SOCK_STREAM,0))== -1)
  {
  perror("socket";
  exit(1);
  }
their_addr.sin_family =AF_INET;
their_addr.sin_port  =htons(PORT);
their_addr.sin_addr  =*((struct in_addr*)he->h_addr);
bzero(&(their_addr.sin_zero),;

if(connect(sockfd,(struct sockaddr *)&their_addr,sizeof(struct sockaddr))== -1)
   {
    perror("connect";
    exit(1);
   }
if((numbytes=recv(sockfd,buf,MAXDATASIZE,0)== -1)
   {
     perror("recv";
     exit(1);
   }
  buf[numbytes] ='\0';
  printf("recevied:%s",buf);
  close(sockfd);
  return 0;  
}
产生错误如下：[root@localhost boot]# arm-linux-gcc  -o client client.c
client.c: In function `main':
client.c:49: error: parse error before '{' token
