Error: sys/wait.h: No such file or directory

I’m trying to code a simple shell by C. But i can’t using sys/wait.h. My code same that:

#include <stdio.h>
#include <sys/types.h>
#include <sys/wait.h>
#include <unistd.h>

int main(void) {
    char command[BUFSIZ];
    int status;
    pid_t pid;

    for(;;) {
        printf("simpsh: ");
        if(fgets(command, sizeof(command), stdin) == NULL) {
        printf("\n");
        return 0;
   }

   command[strlen(command) - 1] = '\0';
   if((pid = fork()) == 0)
   execlp(command, command, 0);

   while(wait(&status) != pid)
   continue;

   printf("\n");
   }

}

I’m using dev-C++ and result is:

[Error] sys/wait.h: No such file or directory

What wrong in here? And if anyone have some suggestions for me to create a simple shell by C or C++ please give me some links or codes. thanks!
