Hi ya'all i hope your having a good time. Im testing a litle program using SRGP, but im getting the following errors:

gcc -fpcc-struct-return -I/usr/include/srgp -O2 claseuno.c \
-L/usr/X11R6/lib -lsrgp -lX11 -lm -lpthread -unistd -o claseuno
In file included from claseuno.c:3:
/usr/include/unistd.h:420: error: expected declaration specifiers or ‘...’ before numeric constant
/usr/include/unistd.h:420: error: expected declaration specifiers or ‘...’ before numeric constant
/usr/include/unistd.h:420: error: expected declaration specifiers or ‘...’ before ‘(’ token
make: *** [claseuno] Error 1

Heres my code(its called claseuno.c):

#include "srgp.h"
#undef unsleep
#include "unistd.h"
#include "stdio.h"
#include "stdlib.h"
#include "time.h"

void ventana(void);

int main(void){
pid_t t;
int tuberia[2],n=1;
srand(time(NULL));
pipe(tuberia);
t=fork();
if(t<0){
return 0;
}
if(t){
while(1){
printf("[%d] Escriba el valor de N:",getpid());
scanf("%d",&n);
write(tuberia[1],&n,sizeof(int));
if(n==0){
close(tuberia[1]);
return 0;
}
}
}else{
while(1){
read(tuberia[0],&n,sizeof(int));
ventana();
if(n==0){
close(tuberia[0]);
return 0;
}
}
}
return 0;
}

void ventana(void){
deluxe_locator_measure r;
int x,y;
if(fork()){
SRGP_begin("Ventana",200,200,16,0);
SRGP_setLocatorButtonMask(LEFT_BUTTON_MASK);
SRGP_setInputMode(LOCATOR,EVENT);
while(1){
x=rand()%200;
y=rand()%200;
SRGP_text(SRGP_defPoint(x,y),"hola");
if(SRGP_waitEvent(6)==LOCATOR){
SRGP_getDeluxeLocator(&r);
SRGP_end();
exit(0);
}
}
}
}

and here are the lines from the make file i use to compile:

# This sample Makefile allows you to make any SRGP application
# whose source is exactly one .c file.
#
# To use this Makefile, you must type:
#
# make PROG=xxxx
# ----
# where
# xxxx.c is the name of the file you wish to compile.
# ----
#
# This is a local version which works cleanly on Linux and Unix, 6/10/2000

CC = gcc

GCCFLAGS = -fpcc-struct-return
CFLAGS = -O2

INCLUDE = -I/usr/include/srgp

LDLIBS = -lsrgp -lX11 -lm -lpthread
LDFLAGS = -L/usr/X11R6/lib


$(PROG):
$(CC) $(GCCFLAGS) $(INCLUDE) $(CFLAGS) $(PROG).c \
$(LDFLAGS) $(LDLIBS) -o $(PROG)

I hope you can help me,i dont know how to solve this. Anyway, if i comment the "unistd.h" include directive, and all functions related to it the error dissapears....its an open suse unistd.h wrong or what?, Thanx
