The code below is fairly straight forward; it copies one structure to
another and sends it to a server on port 7000, the additional header
file that is "info.h" compiles fine and is only used to provide the
structure that is to be copied. (If info.h is needed I'll be happy to
post it)

#include "stdio.h"
#include "unistd.h"
#include "stdlib.h"
#include "string.h"
#include "sys/types.h"
#include "sys/socket.h"
#include "netinet/in.h"
#include "netdb.h"
#include "arpa/inet.h"
#include "ctype.h"

#include "info.h" /*Header the provides the run() function see for(;;)
*/

#define SIZE sizeof(struct sockaddr_in);
struct sockaddr_in server;

int main(void){
        int sockfd;
        info *inf = NULL;

        memset(&server, 0, sizeof(server));
        server.sin_family = AF_INET;
        server.sin_addr.s_addr = inet_addr("127.0.0.1");
        server.sin_port = 7000;

        inf = (info *)malloc(sizeof(info));
        if(inf == 0){
                perror("malloc() :");
                exit(EXIT_FAILURE); }

        if((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1)
        {
         perror("socket() failed!");
         exit(EXIT_FAILURE);
         }

        if(connect(sockfd, (struct sockaddr *) &server, SIZE) == -1)
        {
         perror("connect() failed");
         exit(EXIT_FAILURE);
         }

        for(;;){
                write(1, "gathering", 10);
                *inf = run(); /*copies a returned structer to the inf
structure*/
                send(sockfd, inf, sizeof(inf), 0);
                write(1, "sent", 4);
                }
        close(sockfd);
        return 0;
}

When compiled using a recent version of gcc (4.0.0 or 3.4.4) it
compiles fine, if however it's compiled using gcc 2.95.3 I get the
following errors:

client.c: In function `main':
client.c:44: parse error before `;'

client.c:57: warning: parameter names (without types) in function

Apart from the unused header files, what am I doing wrong? Any
suggestions will be much appreciated

Thank you,
