Probleme de compilation

Bonjour, je veux compiler ce programme :

#include <netdb.h>

#include <netinet/in.h>
#include <sys/socket.h>

#define DEBUG 1
#define TRACKING 0

#define PACKET_SIZE 1024
#define MAX(a,b) (a<b?b:a)
#define FSET(a,b,c) (FD_ISSET(a,c)?a:b)
#define NFSET(a,b,c) (FD_ISSET(a,c)?b:a)

Il me met l'erreur suivant :

gpsd.c:1: error: stray '\357' in program
gpsd.c:1: error: stray '\273' in program
gpsd.c:1: error: stray '\277' in program
gpsd.c:1: error: syntax error at '#' token
gpsd.c:1: error: syntax error before '<' token
make: *** [obj/gpsd.o] Fehler 1

K'ai vraiment pas compris pourquoi
Quelqu'un pourra m'aide ?
