You mean something like this?

#include <spawn.h>
extern char **environ;
int isystem(char *cmd) {
    pid_t pid; int status;
    char *argv[] = {"sh", "-c", cmd, 0};
    status = posix_spawn(&pid, "/bin/sh", 0, 0, argv, environ);
    if (status == 0) {
        if (waitpid(pid, &status, 0) == -1) {
            // perror("waitpid");
        }
    }
    return status;
}
#define system(s) isystem(s)
